Alexander out with head injury

LSU senior cornerback Zy Alexander will not return against UCLA.

Alexander was evaluated for a concussion in the second quarter after making a sideline tackle.

Another member of the Tiger secondary, safety Jardin Gilbert, has returned to the sideline for the second half of the game. He is questionable to return to the game. Freshman DeShaun Spears and senior Sage Ryan will be the primary safeties.
