Oklahoma State head coach Mike Gundy came under fire this week after he was spotted an OAN (One America Network) shirt while on a fishing trip. That photo caught the attention of several OSU football players, including running back Chuba Hubbard, who then threatened to sit out until things changed within the program.

After issuing a few statements and apologies earlier this week, Gundy spoke with ESPN about his mistake wearing the shirt. He admitted to not knowing OAN’s stance on several topics and said he understands why his players would be frustrated with him.

“I didn’t know some of the stances that they had taken. I didn’t know that,” Gundy told ESPN. “And then you look at it and say ‘OK, I was a dumbass.’ I put the shirt on not knowing enough about the shirt.”

When Hubbard saw the photo of Gundy wearing the shirt, he immediately took to Twitter to voice his frustration. He received plenty of support from current and former players, as well.

““I will not stand for this,” Hubbard wrote on Twitter. “This is completely insensitive to everything going on in society, and it’s unacceptable. I will not be doing anything with Oklahoma State until things CHANGE.”

Shortly after Hubbard’s tweet, Gundy and the running back released a video together, vowing to create change within the program.

“I understand exactly why the players got frustrated,” Gundy said.

“The way the players feel about me, and the way I upset them and broke their heart, that bothered me more than losing games. That’s the truth. But that’s why, now, as humans, when we make mistakes — the only thing we can do is admit we’re wrong, own up to it, be humble, accept critical people and criticism, make it better and move forward.”
