Tennessee freshman linebacker Kenny Bynum's season could be in jeopardy after he suffered a torn meniscus.
"He'll be out for a while," Vols coach Derek Dooley said Thursday.
Dooley said Bynum was reviewing his surgery options.
Bynum, from Jacksonville, Fla., signed with Tennessee two weeks after National Signing Day. He had originally committed to Cincinnati.
In other injury news, receiver Cordarrelle Patterson missed practice with a sprained shoulder.
Dooley said the injury was suffered when Patterson fell while attempting to catch a pass and that it was not serious.
Tennessee departs Thursday evening for Milligan College for a week of training-camp-style isolation.
Dooley was sporting a T-shirt that read: "Milligan: Undefeated Since 1950." That was the year the school disbanded its football program.
The Vols practiced indoors Thursday due to heavy rains in Knoxville. Dooley said there is an artificial turf field available for practice in the event of rain at Milligan.
