Jason Kelce had a spirited reaction to his brother Travis Kelce scoring a touchdown during the Kansas City Chiefs-Buffalo Bills playoff game.

For the first time in months, Taylor Swift wasn’t the biggest star in the stands at a Kansas City Chiefs game. This week, it was Jason Kelce.

Coming off a playoff loss last weekend with the Philadelphia Eagles — for whom he plays center — and a week of rumors about his possible retirement, Jason Kelce spent his first weekend off cheering on his younger brother, Chiefs tight end Travis Kelce, in Buffalo.

With just three minutes left in the first half, Travis Kelce made it into the end zone for his first touchdown of the game.

After he chucked the football into the stands, he blew a kiss and made a heart with his hands, appearing to signal that the TD was scored for his girlfriend, Swift, who was watching in a box from above.

Swift promptly celebrated her beau’s success with others in her suite.

Seconds later, in true older brother fashion, Jason Kelce wildly celebrated his little brother’s TD.

Despite below-freezing temperatures and even colder wind chills at Highmark Stadium, Jason Kelce ripped his shirt off to celebrate the scoring drive.

As if that wasn’t enough, the elder Kelce brother proceeded to pound a beer and jump into the crowd below him, where he was met with boos by Bills fans before he hopped back up into the suite.

Both moments went viral almost immediately.

Throughout the game, the camera panned to the star-studded suite, which also featured Jason Kelce’s wife, Kylie Kelce, and Chiefs quarterback Patrick Mahomes’ wife, Brittany Mahomes.
