Michigan linebacker Jaishawn Barham was penalized for unsportsmanlike conduct after making contact with an official during Saturday’s rivalry game against Ohio State.

During the first quarter with the Wolverines leading the Buckeyes 6-0, Barham got close to an official and dipped his head, making contact with the official’s face in the process:

While Michigan was assessed a 15-yard penalty for the violation, Barham was not ejected from the game.

Riding a three-game winning streak over Ohio State in “The Game,” Michigan got off to a hot start Saturday at Michigan Stadium in Ann Arbor.

The Wolverines got on the board first with a field goal on the opening drive, and after intercepting Ohio State quarterback and Heisman Trophy candidate Julian Sayin, No. 15 Michigan extended the lead to 6-0 with another field goal.

Barham’s unsportsmanlike conduct penalty occurred during the No. 1 Buckeyes’ second offensive drive, and Tom Fornelli of CBS Sports speculated that Barham’s headbutt of the official was a result of him attempting to show the official what an Ohio State player did to him.

Despite the penalty, the Michigan defense held firm, stopping OSU on three straight plays from the 2-yard line or closer to force a field goal.

In the midst of his second season at Michigan after transferring from Maryland, Barham entered the weekend with 31 tackles, 10 tackles for loss and four sacks on the year.

After Texas A&M’s loss to Texas on Friday, Ohio State is one of only two remaining undefeated teams in FBS, along with Big Ten rival Indiana.

Last season, the Buckeyes were 10-1 entering their rivalry game against Michigan, and they were shocked 13-10 by a Wolverines team that was only 6-5 at the time.

Still, Ohio State reached the College Football Playoff and won its first national championship since 2014.

The loss to Michigan meant there was still a blemish on the season, though, putting even more pressure on OSU to get the job done this year and finish the regular season with an undefeated mark.
