ANN ARBOR, Mich. (Michigan News Source) – University of Michigan football coach Jim Harbaugh said he expects the four suspended Michigan State football players involved in roughing up two members of Michigan’s team to be punished to the fullest extent of the law.

Meanwhile, the family of Michigan defensive back Gemon Green plans to seek criminal charges in the wake of the tunnel attack Saturday night, and they’ve hired an attorney to help.

“I can’t imagine that this will not result in criminal charges,” the Michigan coach said Monday.

Michigan State coach Mel Tucker said on Monday his players’ behavior was “unacceptable.”

Harbaugh said defensive back Gemon Green was punched by a Spartans player in the Michigan Stadium tunnel to spark the melee shortly after the fourth-ranked Wolverines beat their in-state rivals on Saturday night, and that teammate Ja’Den McBurrows was attacked when he tried to help.

McBurrows is seen on a video shared on social media being pushed, punched and kicked by multiple Michigan State players, who pulled him out of the tunnel and into a hallway that doesn’t lead to either locker room.

Harbaugh said both players have injuries, adding he did not know if Green, a starting cornerback for a third straight season, would be cleared to play Saturday night at Rutgers.

The four MSU football players have been suspended.
