Shirtless Jason Kelce cheers on Travis, Chiefs with Taylor Swift, after pre-game shootout with Bills Mafia [Video]

Jason Kelce was in Buffalo to support his brother Travis and the Kansas City Chiefs.

But he didn’t miss the chance to spend some quality time with the loyal Buffalo Bills. Kelce celebrated with Bills fans before the game and then let off steam in a suite with Taylor Swift as his brother’s Chiefs won a thriller 27-24 to advance to the AFC Championship Game.

The Philadelphia Eagles’ All-Pro center showed up early for the divisional round showdown, making his way to one of the Bills’ many tailgates where he was offered the chance to throw a bowling ball.

Kelce obliged.

Everyone was happy. Kelce exchanged high-fives with Buffalo fans who screamed his name and cheered his exuberance. What a scene.

But fear not, Kelce brothers fans. Jason hadn’t turned on Travis and he wasn’t there to support the Bills on the field. He was later spotted at Highmark Stadium alongside Taylor Swift and wearing Chiefs colors. His loyalty was clearly to his brother on Sunday.

When Travis scored a touchdown in the second quarter, Jason actually howled with joy outside the open penalty box window. He did this with a beer and no shirt. The temperature in Buffalo at that time was 21 degrees.

He then jumped out the window into the stands to celebrate among the Bills fans. Most didn’t seem to appreciate his presence.

Jason remained shirtless and continued drinking beer during Travis’ second touchdown catch, giving the Chiefs a 20-17 lead in the third quarter. This time he let Swift take center stage.

None of this is particularly palatable for Eagles fans. Instead of playing in a divisional round playoff game with Philadelphia, Jason watched one from a luxury box after the Eagles were eliminated from the postseason in the wild-card round last week.

They certainly don’t like seeing Jason wearing the colors of the Chiefs team that defeated their team in the Super Bowl last season. But family comes first, and Jason stood up for his brother on Sunday – and had a great time doing it.
