Oklahoma State has fired offensive coordinator Kasey Dunn and defensive coordinator Bryan Nardo following the Cowboys' 3-9 season, a source confirmed to ESPN on Wednesday.
The Cowboys, who won 10 games last season and reached the Big 12 title game, were expected to be conference and College Football Playoff contenders in 2024 and were ranked No. 17 in the preseason AP poll.
Instead, they went 0-9 in Big 12 play and snapped the program's 18-year bowl game streak under longtime coach Mike Gundy.
Dunn had been a member of Gundy's coaching staff since 2011 and was elevated to offensive coordinator in 2020. Nardo served as defensive coordinator for two seasons after Gundy hired him away from Gannon University, a Division II program.
Significant staff changes were expected after Oklahoma State's nine-game slide resulted in the program's first losing season since 2005. Following a 56-48 loss to Texas Tech in the Cowboys' final home game, Gundy told reporters he had no intention of stepping down.
Gundy, 57, is the third-longest tenured head coach in FBS.
"There ain't no way that the old lady is letting me retire, if that's what you're asking me," Gundy said. "I have as much energy now as I did when I took this job. ... Even though we're in a really tough situation here that we haven't been in in 18 years, I'm excited to come to work tomorrow and try to find a way to beat Colorado."
The Cowboys closed their season with a 52-0 road loss to the No. 25 Buffaloes, the largest margin of defeat in Gundy's tenure.
The Cowboys returned All-America running back Ollie Gordon II, seventh-year senior quarterback Alan Bowman and eight more starters on offense, but struggled to match their production from 2023 and scored 22 points per game in Big 12 play.
Gordon, the FBS leader in rushing yards last year with 1,732, finished with 880 rushing yards as a junior. Bowman was benched late in the season for true freshman Maealiuaki Smith.
Nardo had a successful first season in Stillwater after making the leap from the D-II ranks, but the Cowboys slid to 126th in the FBS in scoring defense (35.6 points per game) and second-worst nationally in total defense while struggling with injuries to several key contributors, including All-Big 12 linebackers Collin Oliver and Nick Martin.
