Kyrie Irving admits it. He used some nasty language toward a Philly fan last Friday night during the game against the 76ers. The NBA has fined the Boston Celtics guard $25,000 because of it.

As the C's were walking into the tunnel to go into halftime, video shows a fan shouting questions about Lebron at Irving. He had a profane response and the league says that is a no-no.

Irving says he has no regrets with what he did.

The Celtics are back home tonight taking on the NY Knicks.
