ESPN analyst Bob Griese can't stop apologizing for the racial slur he made on air during a college football game Saturday about NASCAR driver Juan Pablo Montoya.

The football commentator was promoting Sunday's NASCAR race and the network displayed a graphic with the top five drivers.

Another commentator, Chris Spielman, asked "Where's Montoya?"

"Out eating a taco," Griese responded.

Realizing the personal foul, Griese apologized twice before the Ohio State-Minnesota game ended.

"Juan Pablo Montoya is one of the best drivers in NASCAR," he said just before the end of the game. "I just want to apologize for the comment I made earlier in the ballgame."

"It was regrettable and I should not have said it. I really enjoy NASCAR and I follow it closely and would like to take this opportunity to apologize to Juan, NASCAR and everyone else who heard my comment."

The on-air flap came amidst a series of embarrassing incidents for ESPN, including the revelation that baseball commentator Steve Phillips was bedding a 22-year-old production assistant.

ESPN released a statement right after the football game, calling Griese's comment "inappropriate."

"Bob apologized during the telecast, and plans to apologize again during ESPN's college football programming after his plane lands. ESPN has spoken to Bob and he understands that his comment was uncalled for."
