I. INTRODUCTION
Frederick and Frances Delano (collectively, the “Delanos”) initiated a product liability action against Abbott Laboratories (“Abbott”). The Delanos allege that Frederick Delano (“Delano”) was injured by Abbott’s failure to warn about the increased risk of acquiring histoplasmosis, a fungal infection, when Abbott’s drug Humira is administered with a complimentary drug in the Mississippi valley, a region with high exposure to the histoplasma'fungus. • Abbott has moved for summary judgment, arguing that the Delanos’ product liability claims are time-barred, while the Delanos claim that Abbott waived the limitations period on their claims.
A. Procedural Posture
The Delanos brought, suit against Abbott on June 12, 2011, alleging strict liability, negligence, and breach of warranty claims. Compl. ¶¶ 81-86, ECF No. 1. On September 6, 2011, Abbott moved for summary judgment. Def. Abbott Labs.’ Notice Mot. Summ. J. (“Abbott Mot. Summ. J.”), ECF No. 9. At the same time, Abbott filed an unopposed motion for extension of time to file an answer in light of its motion for summary judgment. Def. Abbott Labs.’ Unopposed Mot.

Abbott Labs.’ Resp. Pis.’ Statement Add’l Undisputed Facts, ECF No. 32-1.
[890]*890On January 19, 2012, the Delanos filed a motion to dismiss without prejudice, requesting that they be permitted to proceed with the case in a parallel suit in an Illinois state court. Pis.’ Mot. Dismiss Without Prejudice, ECF No. 37. The Delanos filed an amended motion to dismiss on June 7, 2012, noting that their action could be consolidated with seventeen other Humirarelated cases against Abbott in Illinois. Pis.’ Am. Mot. Dismiss Without Prejudice 1, ECF No. 43.
This Court allowed the Delanos to amend their motion to dismiss and denied the original motion as moot. See Order, Aug. 29, 2012, ECF No. 47. On September 28, 2012, this Court heard oral argument on Abbott’s motion for summary judgment and the Delanos’ amended motion to dismiss. Clerk’s Notes, Sept. 28, 2012, ECF No. 50. After hearing oral argument, this Court denied Abbott’s motion for summary judgment and granted the Delanos’ motion to dismiss. Order, Sept. 28, 2012, ECF No. 51.
This opinion further explains the Court’s rationale for denying Abbott’s summary judgment motion. See Fed.R.Civ.P. 56(a) (“The court should state on the record the reasons for ... denying the motion.”). When denying in its entirety a motion for summary judgment, I usually ignore this exhortation, as writing takes time and causes delay — the bane of the federal judicial system. I prefer instead the admonition of my great colleague, Judge Joseph Tauro: “What part of the word ‘denied’ don’t you understand?” See also D. Brock Hornby, Summary Judgment Without Illusions, 13 Green Bag 2d 273, 288 (2010) (“[WJhen in doubt on facts or their inferences, judges should ‘just say no.’ ”).

Id. ¶¶ 19, 20; Compl., Ex. B., FDA News Release, ECF No. 1-2.
In a September 4, 2008, letter, the FDA notified Abbott “of new safety information [it] believe[d] should be included in the labeling for Humira ... and which pertains to the risk of histoplasmosis with the use of the class of TNF-inhibitors.” Def.’s Facts ¶ 22 (first and second alterations in original) (quoting Abbott Mot.

Abbott claims that the Humira label was revised in December 2008 in response to the FDA’s request, id. ¶ 21, but the Delanos dispute whether the revised label was distributed or made available to doctors and patients, Pis.’ Facts ¶ 21.
On February 2, 2009, a nurse’s phone record notes that Delano “[s]topped his humira recently as he thought it wasn’t working and possibly making him worse.” Def.’s Facts ¶ 26 (alteration in original) (quoting Abbott Mot. Summ. J., Ex. 3, Veteran Affairs Medical Records (“Medical Records”) FD10001013) (internal quotation marks omitted). Delano’s medical record from February 2, 2009, indicates that he said he “ha[d] been feeling dizzy and unsure of himself .... [was] having difficulty sleeping, diarrhea, headaches and nausea and poor appetite .... [and] thinks (sic) is reaction to his medication Humira.” Id. ¶ 27 (quoting Medical Records FD0001001) (internal quotation marks omitted).

A physician’s note from February 25, 2009, states: “Pt. [Delano] here today with wife states he is to take sporonox now for next 6 months. States this illness occurred after he started taking humara (sic) for his psoriatic arthritis last fall.” Id. ¶ 30 (second alteration in original) (quoting Medical Records FD000090506) (internal quotation marks omitted).
The first communication between Arnold Vickery (“Vickery”), the Delanos’ counsel, and Abbott’s counsel about the Delanos’ claims occurred in May 2010. Id. ¶ 34. Thereafter, the Delanos claim that “[p]ursuant to an agreement between the parties, the statute of limitations was tolled.” Id. ¶ 32 (alteration in original) (quoting Compl. ¶ 6) (internal quotation marks omitted). The Delanos claim that this “informal tolling agreement” was “extended several times,” including in an email written on November 15, 2010, from John Donley (“Donley”), then-lead counsel for Abbott. Pis.’ Facts ¶ 53; Pis.’ Facts, Ex. 3, Email from Donley, Partner, Kirkland & Ellis LLP, to Vickery, Partner, Perdue Kidd & Vickery (Nov. 15, 2010, 9:10 AM) (“Abbott Email”), ECF No. 25-2. Consequently, Vickery believed that Abbott would not assert limitations on the Delanos’ claims. Pis.’ Facts ¶ 53. Specifically, [892]*892Vickery wrote to Donley on November 12, 2010:
John, Karin is nudging me on tolling expirations on Delano, Allen, Schmidt, Dominguez, and Pletan.2 Meanwhile, we are sending letters today and/or Monday with time limits to 12/10 on a couple of our outstanding demands.
If you think that 1/31/11 is enough time, would you please confirm tolling on these claims until that date? Thanks. Andy [Vickery]
Pis.’ Facts, Ex. 3, Email from Vickery, Partner, Perdue Kidd & Vickery to Donley, Partner, Kirkland & Ellis, LLP (Nov. 12, 2010, 5:15 PM) (“Vickery Email”), ECF No. 25-2. Donley replied, “I understood from our previous discussion that no claim was being asserted by Dominguez. Extension of the previous tolling agreement regarding statute of limitations, until January 31, 2011, on all of the other cases mentioned below is hereby agreed by Abbott.” Abbott Email. The Delanos suggest that this email supports their contention that Abbott waived the statute of limitations. See Pis.’ Facts ¶¶ 42, 53. They claim that unlike a tolling agreement between Abbott and another plaintiff represented by Vickery, the informal agreement referenced in Donley’s email did not limit or impose conditions on Abbott’s waiver of the statute of limitations defense. See id. ¶¶ 35, 42, 53. Further, in two other cases, Vickery claims that Abbott, through Donley, agreed to waive the limitations defense if the plaintiffs in those cases consented to Abbott’s choice of forum. Id. ¶ 43. Donley and an Abbott executive met with the Delanos and interviewed them on June 23, 2010; the Delanos claim that Donley acknowledged that Abbott benefitted from not having lawsuits filed yet because suits can “generate bad publicity or attract other litigants.” Id. ¶ 40. Both sides initially agreed that September 30, 2010, would be an appropriate date to have settlement discussions, but decided that the “informal process” would take longer. Id. ¶ 41. According to the Delanos, Donley made a monetary settlement offer in late November or early December 2010. Id. ¶ 44. During this time period, Donley also indicated that Abbott wanted to resolve claims like those brought by the Delanos on a pre-suit basis. Id. “Nothing was said about any potential statute of limitations issue affecting valuation of the case.” Id. In May 2011, Donley introduced Vickery to Abbott’s new lead counsel for the case. Id. ¶ 52. The Delanos filed this personal injury product liability action on June 12, 2011. Def.’s Facts ¶ 1.
C. Federal Jurisdiction
This Court has diversity jurisdiction over this case under 28 U.S.C. § 1332. The Delanos are residents and citizens of Tennessee, and Abbott is an Illinois corporation with its principal place of business in Abbott Park, Illinois. Compl. ¶¶ 3-4. The amount in controversy is substantially more than $75,000. Id. ¶ 5.
II. ANALYSIS
A. Legal Standard
Summary judgment is appropriate where the movant shows that “there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a). A factual dispute is “genuine” if a reasonable trier of fact could find for the non-moving party based on the evidence. Anderson v. [893]*893Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). A fact is “material” if it can affect the outcome of the case under governing law. Id. “The evidence of the non-movant is to be believed, and all justifiable inferences are to be drawn in his favor.” Id. at 255, 106 S.Ct. 2505. The moving party bears the burden of showing that no genuine issue of material fact exists. Celotex Corp. v. Catrett, 477 U.S. 317, 330, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (Brennan, J., dissenting) (citing 10A Charles Alan Wright et al., Federal Practice and Procedure § 2727 (2d ed.1983)). Except for facts admitted by both parties, the Court “must disregard all evidence favorable to the moving party that the jury is not required to believe.” See Reeves v. Sanderson Plumbing Prods., Inc., 530 U.S. 133, 151, 120 S.Ct. 2097, 147 L.Ed.2d 105 (2000). Thus, on issues as to which the moving party bears the burden of proof, the Court will disregard evidence, even if unchallenged, favorable to the moving party that the jury is free to reject. See id.
B. Application of Tennessee’s Statute of Limitations for Product Liability Claims
The Delanos bring three claims against Abbott: strict liability, Compl. ¶¶ 81-84, negligence, id. ¶ 85, and breach of warranty, id. ¶ 86. Tennessee has a statute of limitations and statute of repose that apply to all product liability actions. Greene v. Brown & Williamson Tobacco Corp., 72 F.Supp.2d 882, 886 (W.D.Tenn.1999) (McCalla, J.); see Tenn.Code Ann. § 28-3-104 (statute of limitations); Tenn.Code Ann. § 29-28-103 (statute of repose). As defined by statute, product liability actions can be brought for personal injury, death, or property damage arising out of a wide range of activities, including the manufacture, warning, marketing, packaging, or labeling of any product. Tenn.Code Ann. § 29-28-102(6).
Product liability action includes, but is not limited to, all actions based upon the following theories: strict liability in tort; negligence; breach of warranty, express or implied; breach of or failure to discharge a duty to warn or instruct, whether negligent, or innocent; misrepresentation, concealment, or nondisclosure, whether negligent, or innocent; or under any other substantive legal theory in tort or contract whatsoever....
Id. (internal quotation marks omitted). Accordingly, all of the Delanos’ claims are covered product liability actions under Tennessee law.
Product liability actions “shall be commenced within one (1) year after the cause of action accrued.” Id. § 28-3-104(a). In product liability cases, “the cause of action for injury to the person shall accrue on the date of the personal injury, not the date of the negligence or the sale of a product.” Id. § 28-3-104(b)(l). “The statute of limitations commences to run when the plaintiff knows or has reason to know of the injury which is the basis of his action.” Ball v. Union Carbide Corp., 385 F.3d 713, 721 (6th Cir.2004) (quoting Sevier v. Turner, 742 F.2d 262, 273 (6th Cir.1984)) (internal quotation marks omitted). “A plaintiff has reason to know of his injury when he should have discovered it through the exercise of reasonable diligence.” Id. (quoting Sevier, 742 F.2d at 273) (internal quotation marks omitted). The Delanos’ claims are thus subject to a one-year statute of limitations. See Tenn.Code Ann. § 28-3-104.
Abbott argues that because Delano knew he was ill and believed his illness was caused by Humira on February 2, 2009, his claims accrued then, at the latest. Abbott Mem. 11. Thus, because the Delanos filed suit in June 2011 — over a year [894]*894after their claims expired in February 2010 — their claims are time-barred. Abbott Mem. 12. The Delanos argue that the accrual of their claims does not matter as Abbott waived the statute of limitations through counsel, pointing to the November 2010 email from Donley, Abbott’s counsel.3 Pis.’ Mem. 7.
C. Impact of Tolling Agreement on Abbott’s Statute of Limitations Defense
In diversity of citizenship actions, “state law defines the nature of defenses.” Montgomery v. Wyeth, 580 F.3d 455, 468 n. 7 (6th Cir.2009). Unlike a statute of repose, the statute of limitations can be waived. Hayes v. Gen. Motors Corp., No. 95-5713, 1996 WL 452916, at *4 (6th Cir. Aug. 8, 1996) (per curiam) (“The running of a statute of limitations nullifies a party’s remedy, and, as such, it is a procedural mechanism and .may be waived.” (quoting Bruce v. Hamilton, 894 S.W.2d 274, 276 (Tenn.CtApp.1993))). “A statute of limitation may be waived by express contract or by necessary implications, or its benefits may be lost by conduct invoking the established principles of estoppel in pais.” City of Kingsport v. SCM Corp., 352 F.Supp. 287, 288 (E.D.Tenn.1972). In general, the waiver of a legal right requires “a clear, unequivocal, and decisive act of the party showing such a purpose, or acts amounting to an estoppel on his part.” Jenkins Subway, Inc. v. Jones, 990 S.W.2d 713, 722 (Tenn. Ct.App.1998) (quoting Charleston, S.C., Mining & Mfg. Co. v. Am. Agric. Chem. Co., 126 Tenn. 18, 150 S.W. 1143, 1146 (1911)) (internal quotation mark omitted). A waiver can be proven by express declaration, acts, or a course of conduct reflecting an intent not to claim an advantage. Id. (quoting Baird v. Fidelity-Phenix Fire Ins. Co., 178 Tenn. 653, 162 S.W.2d 384, 389 (1942)). A party claiming waiver must prove it by a preponderance of the evidence. Id.
The Delanos claim that Abbott waived the statute of limitations, as evinced in an email in which Abbott’s counsel extends a “previous tolling agreement regarding the statute of limitátions[ ] until January 31, 2011.” Abbott Email. The Delanos initiated this action on June 12, 2011 — within the period during which the parties’ agreement tolled the statute of limitations. Def.’s Facts ¶ 1.
Even so, Abbott argues that the tolling agreement cannot save the Delanos’ claims because the Delanos first contacted Abbott about' their claims in May 2010, which is [895]*895three months after the one-year limitations period had run. Reply 1-2; see Pis.’ Facts ¶ 37. Thus, any purported tolling agreement cannot save claims that were already expired at the time that the agreement was reached. Reply 3.
It does not follow, however, that a tolling agreement cannot save an expired claim. In Tennessee,, defendants can agree to waive the statute of limitations through tolling agreements. Tenn-Fla Partners v. Skelton, 233 S.W.3d 825, 829 (Tenn.Ct.App.2007). A tolling agreement is a contract, and courts must ascertain the parties’ intent in interpreting such agreements. Id. (noting that tolling agreement is governed by contract law); see, e.g., Monaco v. Bear Stearns Cos., No. CV 09-05438 SJO (JCx), 2011 WL 4059801, at *14 (C.D.Cal. Sept. 12, 2011) (observing that courts generally treat tolling agreements as contract); Joyce v. DLA Piper Rudnick Gray Cary LLP, 382 Ill.App.3d 632, 636, 321 Ill.Dec. 138, 888 N.E.2d 657 (2008) (using “well-established contract principles” to interpret tolling agreement). Thus, the terms of tolling agreements, interpreted under contract principles, determine whether time-barred claims are revived. See, e.g., United States v. Hitachi Am., Ltd., 172 F.3d 1319, 1334 (Fed.Cir. 1999) (concluding that defendant had waived limitations period for both expired and unexpired claims where parties’ agreement stated that “[defendant] will not assert any statute of limitations defense in any action”); SPPI-Somersville, Inc. v. TRC Cos., Nos. C 04-2648SI, 07-5824 SI, 2009 WL 2390347, at *6, *7 (N.D.Cal. Aug. 3, 2009) (rejecting defendant’s argument that tolling agreement is “irrelevant” because limitations period had already expired when agreement was executed and holding that agreement tolled statute of limitations on expired claims because it specified that limitations period was tolled as of an earlier-date, not date of agreement); Union Bank of Switz. v. HS Equities, Inc., 457 F.Supp. 515, 520-21 (S.D.N.Y.1978) (holding that plaintiffs claims were timely where parties agreed to extend statute of limitations, including for a claim that had been time-barred for over a year when agreement was signed, because of agreement’s “broad and plain language” that applied extension to “any claims,” id. at 521). A federal district court, applying Tennessee law, held that a tolling agreement did not revive expired claims where the agreement, by its own terms, stated that it “shall not be deemed to revive any claims that are already time-barred by the time of the Agreement.” O’Boyle v. Shulman, No. 3:09-CV-169, 2010 WL 1408444, at *1 (E.D.Tenn. Apr. 4, 2010) (internal quotation mark omitted).
Here, the Delanos point to a written email from Abbott’s counsel that purports to toll the statute of limitations on their claims, extending the time to file suit from a prior tolling agreement. Abbott Email. Specifically, Vickery, the Delanos’ counsel, wrote Abbott’s counsel to “confirm tolling” on claims in four cases, including the Delanos’ case. Vickery Email. Abbott’s counsel responded, “I understood from our previous discussion that no claim was being asserted by Dominguez. Extension of the previous tolling agreement regarding statute of limitations, until January 31, 2011, on all of the other cases mentioned below is hereby agreed by Abbott.” Abbott Email (emphasis added). The extension does not limit the claims to which it applies, and the email is consistent with the Delanos’ position that Abbott had previoúsly waived the statute of limitations defense for a specific time frame in an informal tolling agreement reached by Abbott’s counsel and Vickery. See Pis.’ Facts ¶ 42; Anderson, 477 U.S. at 255, 106 S.Ct. 2505 (noting that court must draw all rea[896]*896sonable inferences in favor of non-moving party on summary judgment motion); Tenn-Fla Partners, 233 S.W.3d at 829 (commenting that tolling agreements can waive statute of limitations defense).
Further, asserting that a claim is time-barred by the statute of limitations is an affirmative defense. See Mills v. Fulmarque, Inc., 360 S.W.3d 362, 365 (Tenn.2012). So, in a prediscovery summary judgment motion based on an affirmative defense, Abbott, the moving party, has a higher evidentiary burden than merely showing that the Delanos, the non-moving party, cannot sustain their burden of proof at trial. Calderone v. United States, 799 F.2d 254, 259 (6th Cir.1986) (quoting William W. Schwarzer, Summary Judgment Under the Federal Rules; Defining Genuine Issues of Material Fact, 99 F.R.D. 465, 487-88 (1984)). Rather, Abbott must demonstrate that “no reasonable trier of fact could find other than for the moving party.” Id. (quoting Schwarzer, supra, at 259); see also Celotex, 477 U.S. at 331, 106 S.Ct. 2548 (Brennan, J., dissenting) (noting that where party moving for summary judgment bears burden of persuasion at trial, “that party must support its motion with credible evidence ... that would entitle it to a directed verdict if not controverted at trial”); Arvest Bank v. Byrd, 814 F.Supp.2d 775, 792 (W.D.Tenn. 2011) (Mays, Jr., J.) (observing that movant with burden of persuasion at trial must make stronger showing at summary judgment and introduce evidence that would “conclusively establish ” movant’s right to judgment after trial if nonmovant fails to rebut evidence, id. (quoting 11 James William Moore, Moore’s Federal Practice § 56.13[1], at 56-162 (3d. ed.2010))) (emphasis added). Abbott has not met this higher evidentiary burden; it has failed to rebut evidence suggesting that it agreed to waive the statute of limitations defense through January 31, 2011, on all of the Delanos’ claims. See Def.’s Facts ¶¶ 32-36; Abbott Email. Thus, a fact finder should determine the scope of the parties’ tolling agreement. See Solomon v. Open Hearth Rest., Inc., 1985 WL 4823, at *1 (Tenn.Ct.App. Dec. 31, 1985) (“Generally speaking, the tolling of the statute of limitations is a question of fact to be submitted to the trier of facts.” (citing City of Kingsport, 352 F.Supp. at 288)).
Accordingly, because Abbott bears the burden of proof on the statute of limitations defense, save for the Delanos’ admissions, this Court has disregarded the evidence proffered by Abbott, even if uncontradicted, because the jury would be free to disregard it. See Reeves, 530 U.S. at 151, 120 S.Ct. 2097.4
[898]*898III. CONCLUSION
