Oklahoma State has fired both offensive coordinator Kasey Dunn and defensive coordinator Bryan Nardo after a disappointing 3-9 season.

The Cowboys missed a bowl game for the first time since 2005 in the worst season of the Mike Gundy era and posted the team’s worst winning percentage since 1991.

Dunn was a longtime Oklahoma State assistant, joining the staff as wide receivers coach during the 2011 season. He was promoted to offensive coordinator in 2020 and helped lead the Cowboys to a pair of Big 12 Championship Games in 2021 and 2023. However, the offense fell to No. 13 in the Big 12 in 2024.

Nardo was lauded as a creative hire for Gundy, coming to Stillwater from Division II Gannon University in 2023. He was brought in to help transition the program to the 3-3-5 defense that Iowa State popularized, but was unable to deliver results. In 2024, the Cowboys fielded the worst defense in the Power Four, surrendering more than 500 yards per game.

As part of the restructuring of head football coach Mike Gundy’s contract, his $7.75 million annual salary will be reduced to be redistributed as part of a revenue sharing with players, and his buyout will be reduced. Gun-dy would have been owed $25.3 million had he been fired without cause. Gundy is Oklahoma State’s all-time winningest coach and has led his alma mater to a 169-88 record since being promoted to the role in 2004. Gundy guided the Cowboys to the Big 12 title in 2011, league runner-up finishes in 2021 and 2023, and 18 consecutive bowl appearances before this season, when he recorded his worst record at 3-9 and went winless in conference play.
