Thad Matta will not return as the Ohio State head basketball coach for the 2017-18 season, the university announced.
"While this may be a surprise to many, it's the right thing for our program at this time," athletic director Gene Smith said.
Matta reportedly wanted to keep coaching but has come to terms with Smith's decision.
Matta previously underwent back surgery that left him without a fully-functioning right foot and back complications. He has not ruled out coaching again but told reporters that he is focused on his health and family.
He just finished his 13th season with the Buckeyes. Last year's team missed the NCAA tournament after finishing 17–15. It was Matta's first Ohio State team not to win at least 20 games.
Matta and Ohio State reached the Final Four in 2007 and 2012. He won five Big Ten conference championships and four conference tournament wins.
Matta has a career 439–154 coaching record from his days with Ohio State, Xavier and Butler. He won 337 games with the Buckeyes.
Ohio State has started its search for Matta's successor.
