Tillman injured his ankle last week against Akron midway through the second quarter. With Tennessee having a bye next week, there is optimism that he could return for the Volunteers' next game at LSU on Oct. 8, sources said.
Tillman entered the season as the most productive returning receiver in the SEC and a first-team all-conference preseason selection, and he is considered Tennessee's top receiving threat. In three games this season, the 6-foot-3, 215-pound Tillman had 17 catches for 246 yards and a touchdown.
For the Gators, linebacker Ventrell Miller started despite being a game-time decision with a leg injury.
Miller missed last week's win over South Florida with a lower leg injury.
