Ohio State announced Tuesday that the contract of John Markell, head men’s hockey coach at Ohio State, will not be renewed.

Markell was head coach of the Buckeyes the last 15 full seasons, beginning his tenure as the interim head coach in 1995. He was 280-267-56 in his career at Ohio State. He led the squad to six NCAA tournament berths, most recently in 2009. He also headed the program’s first Frozen Four appearance in 1998 and a CCHA tournament championship in 2004.

Chris Schneider, associate athletics director for sport administration, oversees the men’s hockey program at Ohio State and will conduct a national search to fill the position.
