Stephen F. Austin's Brad Underwood has reached an agreement to become Oklahoma State's next head coach, CBS Sports has learned.

A formal announcement is expected soon.

Underwood concluded his third season as a head coach on Sunday with a last-second loss to Notre Dame in the Round of 32 of the NCAA Tournament. His resume features an incredible 89-14 record with three Southland regular-season titles, three Southland tournament titles, and three trips to the NCAA Tournament.

He advanced in the NCAA Tournament in 2014 and 2016.

Underwood, 52, is a Kansas native and former Kansas State player who also spent six years, from 2006 to 2012, as an assistant at his alma mater working under Bob Huggins and Frank Martin -- meaning Underwood has both played and worked in the Big 12. The KSU graduate was raised just three hours from Oklahoma State's campus. He's replacing Travis Ford, who was fired last Friday after eight seasons at Oklahoma State that featured five NCAA Tournament appearances but zero Sweet 16s.
