Mike Gundy dons wrestling leotard in promo video

Oklahoma State is known for having one of the NCAA's most successful wrestling programs, winning 31 official national championships.

This weekend, No. 1 Oklahoma State hosts No. 2 Penn State in a matchup of blue-blood programs.

To hype up the tilt, Cowboys football head coach Mike Gundy put on a wrestling leotard to encourage fans to come out and watch.

Almost just as importantly, Gundy is still rocking the mullet, which he most recently said was tied to his son's grades.
