LUBBOCK, Tex. (AP) — The Texas Tech men’s basketball coach, Billy Gillispie, has resigned because of health concerns, the university said Thursday, ending a disappointing one-year run at a program he had intended to turn into a powerhouse.

The university and fans had hoped that Gillispie, 52, could orchestrate a turnaround like the ones he put together at Texas-El Paso and Texas A&M. Instead, he led the Red Raiders to an 8-23 record last season.

Gillispie did not immediately return a call for comment.

The move came less than a month after the university announced it was looking into allegations that Gillispie mistreated players last fall.

In January, the university reprimanded Gillispie and the assistant coach Brooks Jennings after a review found the team had exceeded practice-time limits.
