Sean Sheller breaks arm, out indefinitely

UCLA Bruins offensive lineman Sean Sheller has a broken right arm that will require surgery and will be out indefinitely, the school announced Saturday after a 49-20 loss to Texas on Saturday.

Sheller, a sixth-year senior and a starting guard, was injured on a running play near the goal line late in the third quarter. UCLA was trailing 35-13 at the time, but scored two plays later to make it 35-20.

Sheller has already missed two full seasons with injuries. He had a medial collateral ligament tear in his right knee in 2006 and had anterior and medial collateral ligament surgery in 2008 after an off-road vehicle accident.

The NCAA granted Sheller a sixth year of eligibility that allowed him to play this season.

Also, defensive back Andrew Abbott suffered a concussion on a hit to the head in the second quarter and will spend the night in a hospital for observation.
