The world of sport has stood alongside Jason Kelce after video emerged of him slamming a fan’s phone to floor in response to being taunted about his brother.

The older Kelce brother and recently retired NFL star was at Penn State on Saturday for the school’s huge college football game against Ohio State when he was goaded by a fan.

‘Hey Kelce! How does it feel your brother is a f***** for dating Taylor Swift?’ a fan shouted at him.

Kelce continued walking after the homophobic slur before turning around, grabbing the fan’s  phone and furiously slamming it down into the ground. He then picked it back up and said ‘who is the f***** now?’ before walking away.

‘Nah man! I’m with J on this one. You can’t just run up on people saying whatever you want, and acting however you want to! This was BS,’ said NFL analyst Ryan Clark on X.

Jason Kelce slams fan’s phone over disgusting jibe at Travis

Jason Kelce angrily slammed a fan’s phone to the ground after they called Travis a ‘f*****’ 

Kelce then walked away with the guy’s phone before asking him: ‘Who’s the f***** now?’

He continued: ‘Homophobic slurs about this man’s brother for no reason. There should be someone that keeps folks away from J in these cases! You know why tho.’

Dave Portnoy, Barstool Sports founder, was on Kelce’s side, writing on X: ‘Jason Kelce shoulda smashed this guys nose into his brain.’

Portnoy then shared a screengrab of the viral video where the fan has a clenched fist as Kelce threw the phone to the ground.

‘Love this loser clenching his fist after Kelce emasculated him like he was gonna do something,’ he wrote.

Clay Travis, the founder of Outkick who was at the game in question, wrote on X: ‘1. Awesome game. Great scene. Phenomenal time. 2. No one likes phone in face/insult guy regardless of what he is saying.

‘3. If Kelce had smashed his phone or punched him, he’d be in less trouble than for using a gay slur, which is wild. 4. Flicking him off and calling him a b**** or just ignoring him and there’s no story here. 5. Reminds me of Beth Dutton on last season of Yellowstone.’

Kelce also got support from Antonio Brown, who shared the clip and wrote: ‘I mean good for Jason Kelce.

‘There’s comedy & entertainment. And then there’s crossing line wit (sic) family.’

Will Compton, an ex-NFL player who now hosts the  podcast ‘Bussin’ with the boys’, wrote on X: ‘Hell yes Jason Kelce. F*** that dude.’

The Kelce family have not yet responded formally to the incident. Swift, meanwhile, is set to perform in Indianapolis on Saturday night on the second of three shows in the city – her final three Eras Tour dates in the United States.

Jason was furious with his brother being targeted with a homophobic slur  

Kelce had a rude awakening earlier on Saturday when he hilariously missed a field goal just weeks after slamming NFL kickers.

He was invited to take part in Pat McAfee’s famous kicking contest at Penn State on ESPN’s College Game Day show.

McAfee, a former NFL kicker with the Indianapolis Colts, challenges a fan to make a kick every week in exchange for a cash prize.

Last month, on the Kelce brothers’ New Heights podcast, Jason demanded NFL goal posts be narrowed because kickers are having too much influence on games.

In response, McAfee challenged the Philadelphia Eagles legend to try and make a kick in exchange for a $100,000 donation to the hurricane relief fund.

Wearing Timberland boots, Kelce toe punted his effort way to the left of the posts.

McAfee then gave him a second opportunity but Kelce was again way off target in front of hundreds of fans. He hilariously admitted afterwards: ‘I suck at kicking’.
