Just a week after Jason's Philadelphia Eagles were eliminated from the NFL playoffs, the loyal sibling stepped into a suite to root for the boys in red alongside his wife Kylie Kelce and Travis' girlfriend Taylor Swift. As the Chiefs' score went up, Jason stripped down, taking off his T-shirt to match the crowd's high energy. See how Travis' supportive brother brought big team spirit to Highmark Stadium as the Chiefs secured themselves a spot in next weekend's NFL Conference Championships. 01 of 15 Taking It Off Jason Kelce.

During an episode of their podcast New Heights, the Kelce brothers explained that the moniker is inspired by Travis' appearance during "shirts and skins" pickup basketball games. "I had the big beard, I had the long hair, I had the chest hair, back hair, arm hair, leg hair," Travis said during a podcast recording in 2022. "Just a big old yeti out there."

Kathryn Riley/Getty Images For now, he's shared his plan to continue cheering on Travis and the Chiefs. After the Eagles lost, Jason spoke to a reporter about his post-season outlook. “I don’t know, that’s one of the beautiful things about the off-season, it’s unscheduled," he said. "So, you know, obviously my brother’s still in the playoffs. I don’t get to watch him play very often, maybe I’ll get an opportunity to go watch one of those games this week."
