Tenn. R. Civ. P. 50.02
Whenever a motion for a directed verdict made at the close of all the evidence is denied or for any reason is not granted, the court is deemed to have submitted the action to the jury subject to a later determination of the legal questions raised by the motion. Within thirty (30) days after the entry of judgment a party who has moved for a directed verdict may move to have the verdict and any judgment entered thereon set aside and to have judgment entered in accordance with the party's motion for a directed verdict; or if a verdict was not returned, such party, within thirty (30) days after the jury has been discharged, may move for a judgment in accordance with such party's motion for a directed verdict. A motion for a new trial may be joined with this motion, or a new trial may be prayed for in the alternative. If a verdict was returned, the court may allow the judgment to stand or may reopen the judgment and either order a new trial or direct the entry of judgment as if the requested verdict had been directed. If no verdict was returned the court may direct the entry of judgment as if the requested verdict had been directed or may order a new trial.
