Michigan football coach Jim Harbaugh placed the blame on Penn State coach James Franklin for the halftime shouting match between the teams in the tunnel during their Oct. 15 game in Ann Arbor, Mich.

Franklin said after the game that a policy should be in place to prevent future incidents, but Harbaugh told reporters Monday that neither the tunnel nor a policy caused the incident.

“Like you saw, pretty clearly, that (Penn State players) completely stopped. They weren’t letting us get up the tunnel,” Harbaugh said. “And it just seemed like such a sophomoric ploy to try to keep us out of our locker rooms. And (Franklin) looked like he was the ringleader of the whole thing.”

Franklin said he would like there to be a buffer when the teams head to their locker rooms, and that having one tunnel is a problem.

“All there has to be is a two-minute or minute buffer in between the two teams,” Franklin said at the time. “This team is in before that team gets close and however we want to do it. But we’re not the first team that’s had issues like that.”

Harbaugh said he has moved on and is preparing his team to face rival Michigan State on Saturday.
