COOPERSTOWN, N.Y. (AP) — New York Yankees great Reggie Jackson says he’s sorry for using profanity in public after a confrontation with an autograph-seeking fan in Cooperstown.

Jackson took to Twitter to express his regret on Sunday, saying “mad or not” there was no excuse for his language.

The New York Daily News reports Jackson got angry with an autograph-seeker at a restaurant Friday night, saying the man had tried to get multiple autographs in the same day.

Cooperstown police say no charges have been filed. The Associated Press could not immediately reach Jackson for comment.

The annual inductions into the Baseball Hall of Fame are taking place in Cooperstown on Sunday. The event brings out a slew of baseball greats.
