“He hit knees yesterday (at practice with another player). It was not his hip, nothing to do with that,” KU coach Bill Self said.

“He bumped knees yesterday, I mean bad,” the coach added. “To the point he could barely walk. He was a little better today. Doctors said no way he could be effective tonight.”

Award nominee: KU forward Perry Ellis is one of 30 candidates for the 2015-16 Senior CLASS Award.

To be eligible, a student-athlete must be classified as an NCAA Division I senior and “have notable achievements in four areas of excellence: community, classroom, character and competition.”

Each of the 30 candidate classes will be narrowed to 10 finalists in February, and those 10 names will be placed on the official ballot. Ballots will be distributed through a nationwide voting system to media, coaches and fans.
