Smith cleared to play; Nelson questionable

UCLA center Joshua Smith has been cleared to play Thursday against Arizona after completing a full practice Wednesday, but froward Reeves Nelson was again limited by his sprained ankle and will be a game-time decision.

Smith fell to he floor and hit his head last Thursday against California and sat out Saturday against Stanford for precautionary reasons. He passed the test required under the concussion protocol and returned to practice on Tuesday.

Nelson, UCLA leading scorer and rebounder with 13.9 points and eight rebounds a game, sprained his ankle in the middle of the second half Saturday against Stanford. He finished the game, but was in a walking boot over the weekend and practiced in a limited capacity Tuesday and Wednesday.

UCLA plays at Arizona Thursday night at 6 p.m. Pacific. The game is on ESPN2.
