Billy Gillispie has submitted his letter of resignation to Director of Athletics Kirby Hocutt, citing health concerns as his reason for leaving the men's basketball program. Hocutt has accepted the resignation.

"Billy has decided to focus on his health and we wish him a full recovery," Hocutt said. "We are proud of the young men that he has brought to this campus. Billy's decision allows him to concentrate on his well-being and allows us to turn our attention to preparations for the upcoming season."

Gillispie, who was named head coach on March 20, 2011, will be paid for the remainder of this contract year that runs until April 30, 2013.

Texas Tech will search for an interim head coach.
