Kansas coach Bill Self expects junior forward Perry Ellis back from his right knee injury in time for the Big 12 tournament.

"It wasn't anything serious," Self told ESPN. "He'll probably miss a week."

On Thursday, Ellis was officially ruled out for Saturday's game at Oklahoma.

Ellis played 17 minutes in Kansas' 76-69 home victory against West Virginia on Tuesday night before teammate Landen Lucas fell on his leg late in the first half. Ellis underwent an MRI, which showed a sprain.

He is averaging 14.2 points and seven rebounds for the Jayhawks, who clinched the outright Big 12 regular-season title with the overtime victory over the Mountaineers.
