Latest News: Jason Kelce Dresses Up as Fred Flintstone and Downs a Bowling Ball Shot of Gatorade During Monday Night Football… Read More

The ESPN broadcaster mingled with members of the Bills Mafia before the team took on the New York Jets on Monday, Oct. 14

The Monday Night Countdown star, 36, donned a Fred Flintstone costume and joined members of the Bills Mafia for a tailgate before the team’s game against the New York Jets on Monday, Oct. 14.

In video captured before the game, Kelce added a crowning touch of Bills blue to the proceedings with a water buffalo fuzzy hat. Leading the crowd in a “Let’s Go Buffalo” chant, he wore a sash that read “Grand Poobah” across his chest, and was seen downing a shot of Gatorade out of a bowling ball.

Later, while joining his fellow MNC hosts, the retired Philadelphia Eagles center sported the Flintstone orange jumper over a Bills-colored blue suit.

For the former NFL star, hijinks with Bills fans is part of the fun.

Last season, Kelce famously took off his shirt while cheering on his brother Travis Kelce’s Kansas City Chiefs at the Bills’ frigid Highmark Stadium.

“I wanted to take everything off and be out there with the fans,” Jason later explained on their New Heights podcast last year. “I don’t know if I’m wrong in my head, but I feel like taking your shirt off is a Buffalo Bills thing, right?”

Six weeks into the NFL season and his new gig on ESPN, the elder Kelce has already had to defend his exuberant actions.

After a detractor called him a “clown” and compared him to an “adult baby” and “slob” — among other things — for dancing before a recent game while working as a member of the media, Jason pushed back.

“I’ll admit I am all of these adjectives at times, but if you think these are the only words that I represent I highly recommend you watch my documentary on Amazon,” the father of three wrote, referring to his Prime Video Sports documentary Kelce, which premiered in October 2023 on the streaming service.

In an interview with PEOPLE this summer, the broadcaster looked back on his recent retirement and previewed what fans and others could expect from him during the first NFL season in 14 years in which he would not be playing,

“I’ve played in the NFL for a very long time,” he told PEOPLE. “I have not been able to experience it as a fan for the most part. So obviously I’ll be working Monday nights, but that means Sundays are open, Thursdays are open. So I got some time to potentially take in the actual game-day atmosphere from a different lens now that the playing days are behind.”
