It looks like the No. 8 Kentucky Wildcats will be down a man when they challenge No. 2 Michigan in the Midwest Region final on Sunday.

Sophomore seven-foot center Willie Cauley-Stein is doubtful for the big game after injuring his ankle in the Sweet 16 victory over Louisville, according to USA Today.

"He's acting like he thinks he can do something," Calipari said. "He's saying that he may want to give it a try, but he hasn't been out of that boot."

Cauley-Stein has been a force on the defensive end for the Wildcats, leading the team with 106 blocks, and second in rebounds with 6.3 per game.

Instead, the pressure will fall on freshman center Dakari Johnson, who already came up huge in the Louisville win. Johnson netted 15 points and six rebounds in a career-high 31 minutes of play.

Johnson will likely be matched up against Michigan big man Jordan Morgan, a 6-foot-8 forward who’s filled in for the injured Mitch McGary for much of the season. 

Morgan played a serviceable role in the regular season, but has played far better in the tournament, notching two double-doubles to start, and scoring 15 points and seven rebounds in the victory over Tennessee in the Sweet 16.

The winner moves on to the Final Four, where they will face West Region victor Wisconsin next weekend.
