Jason Kelce opted against going shirtless this week — at least so far.

Jason Kelce opted against going shirtless this week — at least so far.

The Philadelphia Eagles center not only pulled out his “Big Yeti” shirt again to cheer for his brother Travis and the Kansas City Chiefs on Sunday — but he also added an extra layer of clothing over that T-shirt.

In a sequel to his viral shirtless celebration last week, Jason, 36, attended the AFC Championship game, where the Chiefs squared off with the Baltimore Ravens.

This time, Jason wore a Chiefs-colored floral button-down over a “Big Yeti” shirt and a Chiefs beanie hat — a stark contrast to his bare-chested look at the Chiefs-Bills game on Jan. 21 — as seen in an Instagram photo posted by Patrick Mahomes’ half-sister Mia Bliss and another from Kansas City Mayor Quinton Lucas.

Jason cheered alongside his wife Kylie Kelce, PEOPLE confirms, and parents Ed and Donna Kelce.

Big Yeti” is a longtime nickname Travis earned in college while playing for the University of Cincinnati.

On the brothers’ joint podcast New Heights, they explained that Travis was given the nickname after playing pickup basketball games shirtless.

“I had the big beard, I had the long hair, I had the chest hair, back hair, arm hair, leg hair,” Travis said on that 2022 podcast episode. “I was just a big ole Yeti out there, man. All the homies on the court were calling me ‘Big Yeti’ — especially ’cause I was a low post player, so I was just down there giving work, handing out work in the post.”
