Posted: 10/01/2010 - OXFORD, Miss. (AP) - Just four games into the season, Mississippi's defense is hurting. Defensive end Kentrell Lockett is out for the season, hobbling around on crutches after tearing his ACL. Safety Johnny Brown has a sore knee. Cornerback Jeremy McGee is recovering from a concussion. And that's bad news for the Rebels, considering they were already having trouble stopping opponents before the rash of injuries. They're giving up 32 points per game, which ranks last in the Southeastern Conference.
