LUBBOCK, Texas (AP) Billy Gillispie says doctors have ordered him to avoid any stress for 30 days to try to bring his blood pressure down. In a text message early Monday, Gillispie confirmed he’d been treated for kidney problems and abnormal headaches while at the Mayo Clinic where he went last week. Gillispie is currently on indefinite sick leave from Texas Tech, which is set to begin practices Oct. 12. Texas Tech athletic director Kirby Hocutt told Gillispie last week that he was no longer to make day-to-day decisions for the basketball program or to engage with it so he can focus on his health. The school had no comment on Monday. Associate head coach Chris Walker is in charge.
