USC linebacker Jabari Ruffin will miss the 2014 season after tearing a ligament in his knee during practice. Ruffin was in position to start at outside linebacker before the injury.
Ruffin sustained the injury when he was tackled during an interception return.
A redshirt sophomore, Ruffin played in 13 games last season, including one start, recording 22 tackles, a sack and a forced fumble.
