Onuaku will be sidelined vs. Butler

SALT LAKE CITY -- Syracuse will be without Arinze Onuaku when the top-seeded Orange play Butler in the West Regional semifinals of the NCAA tournament on Thursday.

"He's getting better, but he's not practicing," Syracuse coach Jim Boeheim said Wednesday. "He will not play."

Onuaku has not practiced since injuring his right leg during a Big East tournament quarterfinal game March 11 against Georgetown. He's missed NCAA victories over Vermont and Gonzaga.

Boeheim would not say whether Onuaku would be available for a potential Elite Eight game if the Orange defeat No. 5-seeded Butler.

"He will not play [Thursday's] game, that's it," Boeheim said. "That's all I've got."
