Bryce Underwood Involved in Sideline Altercation With Michigan Teammate as Wink Martindale Struggles to Contain John Mateer

Tensions boiled over on the Michigan sideline after a missed field goal. The reason? Defensive coordinator Wink Martindale struggled to contain Oklahoma QB John Mateer, and following that, Bryce Underwood and his teammates couldn’t slow him down. At the time, the Sooners led 7-0. And then, following the miss, Oklahoma struck again, pushing the lead to 14-0, with just 22 seconds left in the half. So, frustration was visible. The Wolverines were reeling as Mateer and the Sooners kept the pressure on. And here comes the sideline showdown.

On3 reported a sideline scuffle that had heads turning. Quarterback Bryce Underwood and running back Justice Haynes were at the center of it. The moment was brief, but ABC’s cameras didn’t miss a beat. Well, Underwood prowled the sidelines, eyes locked on Haynes. When he found him, he grabbed Haynes by the left arm, spinning him around. Teammates jumped in fast, stepping between the two before things got out of hand. But drama, tension, and split-second reactions; all captured live. But that’s not all.
