Joshua Smith (concussion) sits out

ANAHEIM, Calif. -- UCLA Bruins center Joshua Smith suffered a concussion during practice Wednesday and was not suited up for the Bruins' Pac-12 game Thursday night against Arizona at the Honda Center.

Smith, a 6-foot-10 sophomore, is averaging 9.4 points and 5.4 rebounds for the Bruins this season. His status for Saturday against Arizona State is uncertain, as he will be further evaluated Friday.

Sophomore Travis Wear, a transfer from North Carolina, started in place of Smith on Thursday. The game was designated as the John R. Wooden Classic, an annual event to pay tribute to UCLA's legendary coach.
