Lute Olson is retiring as Arizona's basketball coach, according to ESPN, specifically Dick Vitale. Arizona is denying the report.
Olson, 74, has a career record of 780-280 at Long Beach State, Iowa and Arizona with a 589-188 mark at Arizona since 1983. Olson did not coach the 2007-08 season for what the school called personal reasons, repeatedly denying it was for health reasons.
Assistant coach Mike Dunlap will take over the program on an interim basis, according to Vitale.
Update (x2): Arizona and Olson confirm the retirement.
