Two undefeated teams got chippy in a close game at halftime.
Michigan went into the half up 16-14 against Penn State at the Big House in Ann Arbor, and as the two teams went into the tunnel to their respective locker rooms there was a whole lot of jawing.
It does not appear as though anything turned physical, but Penn State coaches could be seen working hard to restrain Nittany Lions players from getting into a fight with the Wolverines.
