Jason Kelce apologized during ESPN's “Monday Night Countdown” after a viral video captured a “heated moment” between the retired Super Bowl champion and a fan over the weekend.

The video shows an interaction between Kelce and a heckler outside the stadium where Penn State played Ohio State on Saturday. Kelce was at the game as part of Pat McAfee's Kicking Contest hosted by ESPN's “College GameDay.”

A fan is heard using a homophobic slur towards Kelce about his brother Travis, who is dating Taylor Swift. Jason Kelce turns around, grabs someone else's cell phone and throws it on the ground.

Kelce can then be heard repeating the homophobic slur towards the person.

“I think everyone saw everything that happened this week on social media,” Kelce said at the start of Monday night’s show. “I am not happy with everything that happened. I'm not proud of it. In a heated moment, I decided to meet hate with hate, and I just don't think that's a productive thing to do.”

Kelce added that he tries to live his life “by the golden rule” and treat people with decency and respect, and he will continue to do so even if he didn't achieve success over the weekend.

During a postgame press conference on Saturday, Penn State head coach James Franklin said he wished the interaction had never happened.

“I wanted him to have a wonderful experience,” Franklin said of Kelce. “I saw something I wasn’t very proud of. I wish that hadn’t happened.”

In a statement to CNN, Penn State Police said the investigation into this incident is ongoing.
