Oklahoma State head coach Mike Gundy says he's "disgusted" with OAN's coverage of the Black Lives Matter movement ... and is apologizing for promoting the far-right network on his shirt.
Gundy was pictured wearing the pro-Trump outlet's logo on his shirt while on a fishing trip last week ... which sparked outrage with star players like Chuba Hubbard, who threatened to boycott the school.
Gundy says he met with his team on Tuesday to address the issue ... and now understands he screwed up.
"Our players expressed their feelings as individuals and has team members," Gundy said in a video posted on his Twitter.
