Jason Kelce was filmed smashing a Penn State student's phone to the ground Saturday after a heckler dissed his brother for dating Taylor Swift.
"Kelce -- how does it feel that your brother is a f -- -t for dating Taylor Swift?" a troll could be heard yelling in the background of a video shared on social media.
Immediately after, the former Philadelphia Eagles center turned around and slammed a phone to the ground. The phone appeared to belong to someone standing directly behind him.
Jason then turned back around and walked away with a serious look on his face.
It's unclear whether the phone he smashed belonged to the person who asked the offensive question.
Campus police told Page Six an incident report has not been made and that they have no further information on the incident.
Page Six reached out to reps for Kelce, his brother Travis Kelce and Taylor Swift for comment, but we did not receive immediate responses.
Jason, 36, was at Penn State's University Park campus for "College GameDay" on ESPN.
He was also there to partake in Pat Mcafee's "College GameDay" kicking challenge, which encourages students to attempt to kick a field goal in Vans for big cash prizes.
The NFL star-turned-commentator has always been a supporter of his brother's relationship with Swift.
"We just want to be supportive of him and their relationship and everything that they've got going on because it's so wonderful right now," he told reporters at an Eagles Autism Foundation event in June.
He even supported Swift at one of her Eras Tour concerts in London that same month and watched her perform again in Miami this October.
Despite being such a fan of Taylor, 34, and 35-year-old Travis' romance, he admitted on a radio show in September that the attention the relationship brought him and his family can be "overwhelming."
"It's a lot. There's a lot of people paying attention at all times, which is positive and negative at times," he candidly said.
"But I think that she's built up such a fan base and a contingency and an amount of people that really, really just, like, love her that it's really cool at the same time," he added.
