A Dartmouth coach was so incensed when his team fumbled a punt against Harvard that he punched a hole through the glass at Harvard Stadium on Saturday.

Dion King, a defensive quality control coach for Dartmouth, was located in the press box above the field when he broke the glass, sending shards down below.

King was escorted out of the stadium by security. In a statement, Dartmouth head coach Buddy Teevens said King "let his emotions get the best of him."

"Dion and Dartmouth Football are terribly sorry for his actions and any harm caused by them. We hold ourselves to high standards, and in this instance we failed to conduct ourselves appropriately. Dion, Dartmouth Football, and I apologize wholeheartedly to everyone impacted, as well as to Harvard and Dartmouth," Teevens said.

With Dartmouth ahead 14-0 in the second quarter, Danny McManus fumbled the punt in question, which Harvard recovered and turned into a touchdown after a six-play, 38-yard drive.

Harvard would rally to win, 25-22.
