A Texas Tech athletics official says Billy Gillispie is on indefinite sick leave.
Spokesman Blayne Beal said Monday that Gillispie is taking sick days. It was not clear how long Gillispie will be out.
The school announced Aug. 31 that it had opened an investigation into alleged mistreatment of players by Gillispie. Earlier that day and hours before he was to meet with athletic director Kirby Hocutt, Gillispie called 911 and was taken to a Lubbock hospital.
He told the Lubbock Avalanche-Journal he thought he was having a heart attack or a stroke.
He spent six days at University Medical Center before being released last Thursday.
Jordan Tolbert, the teams leading scorer told ESPN that he didn't want to play for Gillispie if the coach returned, but would play for the assistant coaches.
