On Saturday at the Penn State and Ohio State football game, Jason confronted a fan who called Travis an anti-gay slur.

Viral video from the moment shows Jason walking when the person recording approaches him for a fist bump. Someone offscreen could then be heard shouting, "Hey Kelce, how does it feel your brother's a [F-word] for dating Taylor Swift?"

Jason turned and appeared to say words to the person before taking their phone and slamming it on the ground.

Representatives for Jason didn't immediately return BuzzFeed's requests for comment, but internet users had plenty to say about the moment:
why would you ever even say something like that
— zey ୨୧ (@zeyblvd) November 2, 2024It's not the first time Jason has had to defend Travis, either. He also supported his brother last month when people tried to say his "slow start" this NFL season was because of Taylor, who Travis began dating last year.

"I know optics are that he is all over the place," he told ESPN. But "football has always been the most important thing in Trav's life."
"He has always lived his life to the fullest," Jason added. "He has enjoyed his off-seasons very much even before Taylor Swift and everything else that was going on in our lives."
