Joel Embiid's status uncertain

— -- Kansas center Joel Embiid's status remains uncertain for Saturday's game against  TCU.

"I don't know yet how long he'll be out for, if he'll miss any games," Jayhawks coach Bill Self told ESPN.com on Wednesday. "It's up in the air."

"Will he play against TCU?" Self added. "I don't know yet."

Self said the 7-foot freshman, projected by some as the top pick in June's NBA draft if he elects to leave college after one season, had an MRI on his injured back.

"It didn't come back with anything major," Self said. "He'll be back soon. It's not going to be long."

Embiid injured his back in the waning minutes against West Virginia, but Self said he has also been battling a knee injury for the past couple weeks.

Embiid, who is averaging 10.7 points, 7.8 rebounds and 2.5 blocks in 22.3 minutes per game, has been struggling the last few games and seen his offensive production and minutes drop. He's averaging 7.5 points in 17.3 minutes the last three contests.

Self said Embiid has been limited in practice for the past week.

Kansas is coming off a 85-82 overtime loss Monday night at rival Kansas State, and the team has four days off prior to the game against TCU.

The Jayhawks are 18-6 overall and in first place in the Big 12 with a 9-2 record.
