RALEIGH - John Clougherty, the ACC supervisor of men's basketball officials, said Monday that none of the referees working the N.C. State-Duke game Saturday saw Wolfpack coach Sidney Lowe trying to signal for a timeout in the final seconds.

Lowe said after the Pack's 87-86 loss that he attempted to call a timeout moments after State's Courtney Fells rebounded a missed shot with four seconds to play. Fells dribbled up court and passed to Ben McCauley, who fired up a 25-footer that missed.

"The official was running by me and turned and looked at me,'' Lowe said after the game at the RBC Center. ''I called [a] timeout, and I didn't get it."

Clougherty said he spoke with the three officials -- Les Jones, Brian Dorsey and Ray Perone --about the play in question.

"I called the crew to ask them, and they never saw Coach [Lowe] ask for a timeout," Clougherty said. "I told Coach Lowe that [Monday]-- that Les, Brian and Ray never saw him ask for one.

"I'm not saying that Coach Lowe did not ask for a timeout. It would have been easier if a player had called it. The referees are looking down the floor at the play, and that's where I want them concentrating. But they never saw Coach Lowe."

LOWE'S MOTHER OUT OF HOSPITAL: N.C. State basketball coach Sidney Lowe said Monday that his mother had been released from a Raleigh hospital.

Carrie Lowe suffered a heart attack last Wednesday and was taken to WakeMed.

"She's doing better," Lowe said. "I brought her home Saturday night after the game. She's doing OK. I have to take her back this week for some tests and they will decide if they need to keep her. But she's doing OK."
