John Calipari said last season's consensus National Player of the Year would have a knee procedure.

Calipari didn't give much information on the injury, which he posted about on the social networking site.

"I have good news and bad news, but I'm not sure what to make of it," Calipari wrote. Oscar had a great performance at Pro Day and the scouts liked what they saw. He came back to develop his game and became a more complete player. They liked it very much.

The bad news is I kept him out of practice on Saturday. He didn't want to sit out pro day. He was forced to sit out and be examined as a precautionary measure. He is going to have a small procedure to clean up. There was no dancing at Madness.

The former West Virginia transfer averaged 17.4 points and 15.3 pounds, leading the nation in both categories.

Tshiebwe has just under a month until the season officially starts.

The season opener for Kentucky is against Howard on November 7. Next up for the Cats is a game against Duquesne on November 11.
