CINCINNATI -- Cincinnati men's basketball coach Bob Huggins was undergoing tests Thursday at a Cincinnati hospital to determine how much damage he suffered from a heart attack last weekend.

A statement on the results could be released Friday.

Huggins, 49, remains listed in "serious but stable" condition as he recovers from a heart attack suffered at the Pittsburgh airport on Saturday while on a recruiting trip. He was moved to Christ Hospital in Cincinnati on Wednesday from the Medical Center in Beaver, Pa.

"It came on quick. He was sweating profusely. It was very painful," Cincinnati athletics director Bob Goin said. "Timing was of the essence. Everybody snapped to it. I don't think there was time to spare."

University of Cincinnati officials said there have been no decisions on when Huggins could leave the hospital or return to work. The Bearcats start their practices Oct. 12. Doctors have said Huggins could need 4-to-6 weeks to recuperate.

Cincinnati sports information director Tom Hathaway said this week it was premature to say if associate head coach Dan Peters, a longtime assistant of Huggins' and a former head coach at Youngstown State, would be named interim coach. Peters would be the logical choice since he has more experience than staff assistants Andy Kennedy and Keith LeGree.

Memphis coach John Calipari visited Huggins Sunday in the Pennsylvania hospital and said Huggins was responsive and knew the severity of what had happened. He said Huggins told him the heart attack happened at the curb at the Pittsburgh airport. He was on the phone at the time and dropped it when he fell. But the proximity to the street enabled Huggins to be treated quickly.

Calipari said Huggins told him that someone in the ambulance said to him, 'Coach, I won't let you die. I'm John Calipari's cousin.' Huggins apparently said in jest, even at that moment, 'Oh no. Then I have no chance.' Calipari said he wasn't sure who the person was and never got the name.

After being rushed to the hospital, Huggins had surgery to implant a metal mesh stent to keep a clogged artery open.

Calipairi said Huggins wants to coach this year; whether it is the smartest move is to be determined. He said he visited with Huggins for almost 40 minutes and told him to take care of himself.

"He knows how close he was," Calipari said. "It appears he'll be fine, but I'm not a doctor. I know he'll want to coach this season but if that's the smartest thing, well, I don't know."

Huggins was the third-youngest coach to get 500 wins in Division I. His career record is 500-172, including a 332-100 record at Cincinnati.

The Bearcats have been ranked No. 1 several times during his tenure but have made the Final Four just once. Cincinnati went 31-4 last season, losing to UCLA 105-101 in double overtime in the second round of the NCAA Tournament.
