George Kittle isn’t just a great tight end in the NFL, he’s also an incredibly entertaining individual when there’s a microphone in front of him. And after the San Francisco 49ers clinched a Super Bowl berth with a win over the Green Bay Packers on Sunday, Kittle didn’t hold back.

San Francisco defeated Green Bay 37-20 to claim the NFC Championship and advance to the Super Bowl, where the 49ers will take on the Kansas City Chiefs. After the game, Kittle arrived at the postgame presser wearing a really unique T-shirt over his shoulder pads.

It was a shirtless image of quarterback Jimmy Garoppolo. Oh, and it was signed.

After the game, Kittle said he hadn’t broken out the shirt yet because he was saving it for a big moment. Sunday was definitely the moment to break it out. Below is the clip, as posted by ESPN on Twitter:

49ers fans may start purchasing those shirts after Sunday’s win.

Garoppolo needed to throw just eight passes in San Francisco’s win, completing six for 77 yards. The 49ers’ ground game was working in full force, as Raheem Mostert rushed for 220 yards and four touchdowns.

It should be interesting to see if Kittle has another special T-shirt prepared for a potential Super Bowl victory celebration, if the 49ers defeat the Chiefs in a few weeks.
