Following all of Jason Kelce's shirtless escapades during Chiefs-Bills game

The Kansas City Chiefs beat the Buffalo Bills 27-24 in the AFC divisional round Sunday. But a famous Philadelphia Eagles player is the one making headlines.

Jason Kelce, brother of Chiefs tight end Travis Kelce, went viral on social media after being seen at Highmark Stadium wearing nothing but pants and a beanie hat. The Eagles center also cheered passionately (to say the least) when his brother scored a touchdown in the second quarter of Sunday's game.

Jason sat in a luxury box alongside his brother's pop star girlfriend, Taylor Swift. During the game, he was seen cheering and screaming for the Chiefs while shirtless after Travis scored a second-quarter touchdown. Several fans also saw Jason jump down from his suite, chug a beer and return to his box seat.

The TV cameras later panned to Swift after Travis scored a second touchdown. But, once again, Jason, who was spotted chugging another celebratory beer, took the spotlight, as he was shirtless in the background.

When asked about his brother's viral shirtless moment, Travis stated he didn't know about the stunt but said it didn't surprise him.

"My brother was shirtless? Nah, it doesn't surprise me one bit," Kelce told CBS Sports. "I love that guy, and every time we're not on the field together, we're always rooting for each other."

According to the Daily Mail, last night's game was the first time Jason and his wife, Kylie, were spotted with Swift since her relationship with Travis became public in September.
