Alabama outside linebacker Terrell Lewis will be out for an undetermined amount of time after suffering a torn ACL, the school announced Tuesday.
"Terrell Lewis suffered a torn right ACL last week while training," coach Nick Saban said in a statement. "He underwent successful surgery today, and a timeframe for his return is unknown at this time."
Lewis, who started one game as a sophomore last season, ultimately missed 10 games with an arm injury. A former four-star prospect, he had 16 tackles and a sack.
Alabama's linebacker corp took an additional hit Monday when sophomore VanDarius Cowan was dismissed from the program for violation of team rules.
