Texas Tech basketball coach Bob Knight has retired. Chris Cook, a spokesman for the school's athletic director, says Knight is retiring immediately.
The program will be turned over to his son, Pat Knight, who was named head coach-designate in 2005.
Knight's resignation was first reported by the Lubbock Avalanche-Journal.
Knight has 902 career wins, more than any coach in the history of Division I men's basketball. Win number 900 came last month against Texas A&M.
The 67-year-old has been a head coach for 42 years at three Division I schools. He got his 100th victory at Army, then moved to Indiana, where his Hoosiers went 662-239 and won three national championships from 1971-2000.
His first NCAA title came in 1976 when Indiana went undefeated, a feat no team has done since. In 1984, he coached the U.S. Olympic team to a gold medal in Los Angeles.
