Jason Kelce showed a Penn State football fan Saturday what can happen when he goes too far.

Before the No. 3 Nittany Lions faced No. 4 Ohio State in State College, a fan mocked Kelce with a homophobic slur aimed at his brother Travis and his relationship with pop superstar Taylor Swift.

Kelce, who was in State College to appear on ESPN's “College GameDay,” was followed by a fan who said to him, “Kelce, how does it feel that your brother is a fan because he's dating Taylor Swift.” ?”

The former NFL lineman responded by turning around, grabbing the fan's phone, slamming it to the ground and taking it away.

Here's a clip of the incident from a different angle where the insult can be clearly heard. (Warning: Offensive language can be heard in the video.)

Jason Kelce has been a near-ubiquitous presence in football reporting and advertising this season since retiring after 13 seasons with the Philadelphia Eagles. However, his brother's relationship with Swift, which has made Travis Kelce a major pop culture figure, has significantly increased his public profile.

The Kelce brothers' podcast “New Heights” has since become enormously popular. In August, the two signed a three-year deal worth more than $100 million for an exclusive ad sales and distribution rights agreement with Amazon's Wondery podcast network.

Unfortunately, this popularity and high public profile have also made celebrities like Kelce a target for insults and ridicule from fans looking to provoke a reaction and perhaps create a viral moment on social media.

If that's the fan's intention, then that's certainly what happened on Saturday. However, the incident did not spread in the way the aggressive, obnoxious heckler probably expected. Fans on social media are wondering whether Kelce committed robbery by taking the phone or whether his actions were justified due to the harassment. It is possible that this incident could have repercussions.
