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.
Sophomore linebacker Christian Harris is out after undergoing ACL surgery about four months ago. He's started some light running on the side.
Dooley said depth at inside linebacker is a concern.
"It's a real concern, especially now that we've already lost two (Harris and Bynum) inside pluggers. That's a real concern on our football team and has been," he said.
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.
* Freshman kicker George Bullock, who was brought in to challenge Michael Palardy, has done well, Dooley said.
"He did a nice job in field-goal period and did a good job kicking off for the first time in college, which is hard," Dooley said. "We'll see how he progresses. He has a real mature approach about him."
* Sophomore linebacker Curt Maggitt appreciates the praise from defensive coordinator Sal Sunseri.
Sunseri said earlier this week that Maggitt and fellow sophomore A.J. Johnson are among the finest young linebackers he's coached.
"It means a lot for him to say that. But I'm still trying to get better and take in everything and try and be the best I can be," Maggitt said. "It's the same with A.J. We push each other every day to be the best."
* Sunseri spent extra time after practice in a rather animated conversation with linebackers.
"They had a lot of mental errors and gave up some big plays because of it," Dooley said. "This is the time in camp, with the volume of stuff we're throwing at them, when it's mental error, mental error, mental error."
