Oklahoma State running back and Heisman Trophy candidate Chuba Hubbard has stated that he will not be doing anything else with the school after his head coach Mike Gundy was spotted wearing a One America News (OAN) shirt on a fishing trip.

Hubbard took to Twitter on Monday to announce his frustration and disappointment with the head coach. Gundy was wearing a T-shirt that supported OAN and an image was posted on Twitter. After seeing the photo, the Cowboys running back made his statement.

“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.”

Amen Ogbongbemiga, a linebacker at Oklahoma State, showed support for his teammate.

“I stand with him,” Ogbongbemiga wrote.

Hubbard was a 2,000-yard rusher for the Cowboys last season, racking up 2,094 yards and 21 touchdowns on 328 carries. He also caught 23 passes for 198 yards.
