Tennessee head coach Butch Jones said on his radio show Wednesday night that Bristol native Mack Crowder is a game-time decision Saturday against Florida.
The former Tennessee High Viking has been the back-up center this season.
Jones also said that he won't name a starting quarterback until just before kick-off.
The Vols are facing the 19th ranked Gators Saturday in Gainesville.
Junior quarterback Justin Worley has started every game this season but Jones opened up the competition following Saturday's loss to Oregon.
