LSU linebacker Harold Perkins Jr. injured his knee and was helped off the field in the fourth quarter of the Tigers’ 34-17 home win over UCLA on Saturday. Trainers shuffled him into the injury tent after Perkins was banged up on a tackle attempt and ruled him out for the rest of the game. He left the tent and walked to the locker room under his own power but held his head down with a towel over it. LSU coach Brian Kelly addressed the injury after the game.
