UCLA senior forward James Keefe dislocated his left shoulder for the second time this season in practice today and is questionable for Sunday's game against USC at the Galen Center.

Keefe, the former McDonald's All-American who averages 16 minutes per game, missed three games in December when it happened the first time. It's also the same shoulder he had surgery on in 2007 to repair a torn labrum.

The Bruins did get good news as freshman forward Reeves Nelson is listed as probable for the game after suffering a concussion last week against Cal. Nelson only resumed participating in full-contact practices yesterday.
