conspired to force them to sell their business. In the process of ruling on the issues presented therein, the court expressly held that the complainants’ tort allegations —i.e., the alleged conspiracy which forced them to sell their business—were governed by the three-year statutory limitations period set forth in T.C.A. § 28-3-105.
More recently, in Dorsett Carpet Mills, Inc. v. Whitt Tile & Marble Distributing Co., slip op., 1986 WL 622 (Tenn.App. Jan. 2, 1986), aff'd, in part, rev’d in part, 734 S.W.2d 322 (Tenn.1987), Whitt Tile brought a counterclaim against Dorsett in which it alleged fraudulent inducement of breach of contract, conspiracy, and wrongful interference with business. Judgment was entered in favor of Whitt Tile on its counterclaim. In affirming that judgment, the Tennessee appellate court noted that T.C.A. § 28-3-105’s three-year limitations period governed Whitt’s allegations. . See also Harvest Corp. v. Ernst & Whinney, 610 S.W.2d 727 (Tenn.App.1980) (suits in which fraud, deceit or conspiracy are alleged are actions in tort and are governed by § 28-3-105).
As we pointed out before, the gravamen of UST’s claim in Count 8 is that Busch conspired through various acts of mail fraud, wire fraud and extortion to injure UST’s business. Thus, the damage alleged is injury to business and the means by which that damage was allegedly achieved are conspiracy and fraud. In this regard, we fail to see how UST’s claim is any different from the conspiracy to injure business claim brought by the complainant in Budget Rent-a-Car which the Tennessee Supreme Court expressly held was governed by the three-year limitations period found in T.C.A. § 28-3-105. In light of this Tennessee Supreme Court precedent and the absence of any modern authority instructing to the contrary, we reject UST’s argument that a general “injury to business” doctrine exists in Tennessee mandating the application of T.C.A. § 28-3-110(3)’s residual ten-year limitations period.
In the alternative, UST argues that any applicable statute of limitations on its common law claims was tolled by the duress Busch allegedly exercised over UST in the negotiation and execution of the December, 1980 contract. Because UST did not raise this argument before the district court, the argument has been waived and we need not consider its merit. Gray v. Lacke, 885 F.2d 399, 409 (7th Cir.1989), cert. denied, — U.S. -, 110 S.Ct. 1476, 108 L.Ed.2d 613 (1990); Zbaraz v. Hartigan, 763 F.2d 1532, 1544 (7th Cir.1985).
2. Economic Duress
In dismissing UST’s “economic duress” claim, the district court stated, “[i]t is not clear whether this is a tort claim or a contract claim since plaintiff has not cited any published Tennessee law (nor the law of any other state) to establish that it has a valid claim. The court therefore holds that plaintiff does not have an actionable claim.” Because we conclude the allegation of Count 14 is grounded in tort, and because such an allegation under Tennessee law is governed by the three-year limitations period set forth in T.C.A. § 28-3-105, we affirm the district court’s dismissal of Count 14, albeit on different grounds.
As a general rule, a party who has been induced through duress to enter into an agreement or contract may pursue one of two remedies; he may seek rescission of the agreement in an equitable proceeding or he may affirm the contract and sue for damages at law. Solomon v. Flo-Warr Management, Inc., 777 S.W.2d 701, 705 (Tenn.App.1989) (applying Alabama law); see also Vance, 547 S.W.2d at 931 (same options available to one “fraudulently induced” into entering into a contract); Cureton v. Oberman, CA No. 1339, 1990 WL 97841 (Tenn.App. July 17, 1990); Williamson v. Upchurch, 768 S.W.2d 265, 271 (Tenn.App.1989); Crocker v. Schneider, 683 S.W.2d 335, 338-39 (Tenn.App.1984). UST has not expressly asked either this court or the district court to set aside the December, 1980 contract.9 Rather, UST

The fact that UST did not seek such equitable relief in Count 14 is understandable in light of *1272the six-year delay which UST allowed before filing suit. In Tennessee, a party wishing to set aside a contract must do so within a reasonable period after the grounds for rescission become apparent. "It is a settled rule that the right to rescind a contract for fraud must be exercised immediately upon its discovery, and that any delay in doing so, and the continued employment, use, and occupation of property received under a contract will be deemed an election to confirm it."

Landreth v. Schevenel, 102 Tenn. 486, 493, 52 S.W. 148, 149 (1899));
see also Valley Fidelity Bank & Trust Co. v. Cain Partnership, Ltd., 738 S.W.2d 638, 640 (Tenn.App.1987);
Crocker, 683 S.W.2d at 340;
Williams v. Spinks, 7 Tenn.App. 488, 493 (1929) (a party may lose his right to rescind a contract by not availing himself of his right within a reasonable time after discovering the fraud). Thus, even if UST’s prayer was one for rescission, we would affirm the dismissal of Count 14 on these grounds.
