ESPN analyst Lou Holtz apologized on air today for mentioning Adolf Hitler during a college football studio show the previous night.

The former Notre Dame coach referenced Hitler while making a point about good and bad leadership during a discussion of the struggles of first-year Michigan coach Rich Rodriguez.

"Last night while trying to make a point about leadership, I made an unfortunate reference," Holtz said. "It was a mistake and I sincerely apologize."

An ESPN spokesman said Holtz will not be further disciplined.
