Key Kentucky reserve Willie Cauley-Stein has been ruled doubtful for Saturday's game against Wisconsin by head coach John Calipari due to an ankle injury suffered in the Sweet 16 against Louisville.

"I doubt he plays," Calipari said on a conference call Monday. "He will be on our bench, cheering like crazy."

The 7-foot Cauley-Stein is UK's second-leading rebounder (6.1 per game) behind Julius Randle, but the Wildcats were able to win a pair of games without him last weekend. 

Reserves Marcus Lee and Alex Poythress are expected to play larger roles on Saturday, along with starting center Dakari Johnson.

Lee, Poythress and Johnson combined for 26 points on 12-of-15 shooting in Sunday's win over Michigan.
