A seam in the end zone came loose during the fourth quarter of the Big Ten Championship game, causing a 10-minute delay.

A few minutes later, a maintenance worker started spreading something under the two seams that came apart. He then tried to put the rubber pellets back in place on the goal line. The end zones are new turf, so they are not as stable as the rest of the field. 

Wisconsin's Chris James had scored on a 1-yard run on the play to cut Ohio State’s lead to 24-19 with 12:39 remaining. After the delay, Wisconsin's Alex Hornibrook completed a pass to Troy Fumigalli for a 2-point conversion to trim Ohio State's lead to 24-21.
