Jason Kelce participated in some fun festivities alongside the ESPN “College GameDay” team on Saturday.

But things took an ugly turn after a homophobic comment from a fan outside Beaver Stadium was used in reference to his brother Travis.

The retired Eagles center was seen walking through University Park, Pennsylvania, carrying a case of beer as shouts and cheers could be heard around him from people who recognized the former NFL star.

But one comment stood out from all the noise after a fan made a disparaging comment about Travis Kelce’s high-profile relationship with Taylor Swift.

“Kelce, how does it feel that your brother likes hanging out with Taylor Swift?”

Warning: explicit language

Kelce quickly turned around to find the person who uttered the insulting comment and raised his hand in disbelief.

Realizing who it was, Kelce grabbed the fan’s phone and slammed it to the ground in anger.

Some gasps were heard from the crowd surrounding Kelce, who turned and stormed away.

Kelce has yet to respond on social media about the incident.

Early in the morning, Kelce appeared on the set of “GameDay” with Pat McAfee to attempt a field goal challenge that has become a fun weekly part of the show.

While wearing Timberland boots, Kelce missed both attempts.kicking them wide to the left.
