LUBBOCK, Texas (AP) -- Texas Tech reprimanded coach Billy Gillispie earlier this year after learning he was exceeding NCAA practice-time limits.

Red Raiders athletic director Kirby Hocutt said Wednesday the school reported the secondary violations to the NCAA and the governing body approved the penalty that Texas Tech had decided upon. The reprimand came in January.

The school is now investigating allegations that Gillispie mistreated players, Hocutt said.

Gillispie has been hospitalized since Friday and did not respond to a text message Wednesday seeking comment.

Hocutt said the penalty last season meant the team was docked twice the number of hours per week that Gillispie had exceeded the limit during a two-week period in December.

The NCAA allows 20 hours of practice per week.
