The UCLA Bruins have seemingly gone through it all this season and the team took yet another blow on Thursday as they announced big man Josh Smith will not play against the Arizona Wildcats. Smith suffered a concussion during Wednesday's practice and is in street clothes at the Honda Center.

MBB. UCLA sophomore center Joshua Smith has a concussion and will not play in tonight's Pac-12 game against Arizona. Smith is day-to-day.

This is not good news for the Bruins, although Arizona does not feature too much in the way of a post game. Still, though, UCLA would have had a serious advantage in the paint against their conference foes with Smith in the lineup. It will be interesting to see how Ben Howland and the UCLA coaching staff adjust their rotations against the up-tempo style of the Wildcats.

Expect Travis and David Wear to see even more playing time than usual tonight against UA. Tipoff is set for 8:00 p.m. from Anaheim.
