Texas Tech coach Billy Gillispie said he experienced what felt like a “stroke or a heart attack” before being hospitalized Friday. Gillespie said in an interview for a story published in the Lubbock Avalanche-Journal on Saturday that he called 911 early Friday morning after experiencing severe pain. “It was the worst I’ve ever felt,” Gillispie, 52, told the newspaper. He also said that he was told his blood pressure was dangerously high and that he has been dealing with stress. University Medical Center spokesman Eric Finley told the Associated Press that Gillispie would stay at the hospital Saturday night and is still in satisfactory condition.
