Tough news for the Utes ... it looks like forward Kim Tillie is not going to play tonight -- and could be out awhile, presumably -- after being diagnosed with a stress fracture in his leg.

Tillie twisted his ankle in practice a couple of weeks ago, but continued to play and only today learned the severity of the injury. His long-term prognosis is uncertain, but stress fractures usually keep guys out awhile -- even though coach Jim Boylen is hopeful that Tillie can return sooner rather than later because the injury occurred in a bone that bears less weight than others in his leg.

The 6-foot-9 forward had become a productive reserve for the Utes this season -- he's the best rebounder, per minute, on the team -- averaging 5.9 points and 4.1 rebounds and shooting 62.5 percent in barely 15 minutes per game. He had played in all 10 games this season, after missing the last 18 last season with a broken ankle.

His absence means an even larger opportunity for forward Stephen Weigh, who did not play against Cal last weekend because of match-ups but already figured to get more of a chance against the Bengals.
