Less than a week after firing head coach Mike Gundy, Oklahoma State announced on Sunday that it has also relieved defensive coordinator Todd Grantham of his duties. Offensiive quality control coach Clint Bowen will replace Grantham on an interim basis. Grantham, 59, spent the 2023 season and part of the 2024 campaign as the New Orleans Saints’ defensive line coach before joining Gundy’s staff. Oklahoma State has had four defensive coordinators in the last five seasons, though Bowen brings plenty of experience in the role at Kansas from 2014-18. Clint Bowen spent the previous four seasons coaching football at the high school level.
