Jason Kelce's Outfit Steals the Show at Bills-Jets Game

The Buffalo Bills take on the New York Jets on Monday Night Football, an AFC East showdown with major implications. If the Bills can defeat the Jets in the Meadowlands on Oct. 14, they remain atop the division. If New York wins, they'll tie Buffalo for first place.

Before kickoff, former NFL star Jason Kelce joined Bills Mafia outside MetLife Stadium. Dressed up as Fred Flintstone, he took shots of Gatorade from a bowling bowl. The 36-year-old abstained from drinking as he needed report for duty as an analyst on "Monday Night Countdown."

While Kelce's younger brother, Travis Kelce, plays for one the team's biggest AFC rivals, the retired Super Bowl champ made it clear that he was pulling for the Bills on Monday Night Football.

Kelce appeared on ESPN's pregame show in a blue suit with a red, white, and blue striped tie. However, it was his golden chicken wing necklace that won Bills Mafia over.

One woman posted , "No one quite like @JasonKelce. LOVE this man. Love the suit look, Jason, too."

Former Bills Pro Bowl center Erik Wood also gave the Eagles legend a shoutout for rocking with his fans. He posted, "My man @JasonKelce is a man of the people!"

Kelce started to win over Bills Mafia, and vice versa, during the Chiefs' 27-24 win over Buffalo in the AFC Divisional playoff round last season. After Travis scored a touchdown, Kelce, while rocking a Bills beanie, went viral for his shirtless celebration.

"Here’s what happened," he explained on an episode of " New Heights " in January.

"I wanted to take my shirt off at the tailgate. Because we kind of got pushed back on the tailgate front, I didn’t get to take my shirt off there. And then when I entered the box, I noticed, ‘Hey, I can jump out of this box and I’ll be outside.'"

"And if I take my shirt off and go outside, I’m part of the Buffalo Bills pageantry. It was something about the entire day, I just got caught up in the magic of Bills Mafia. It is electric."
