Jason Kelce made his big TV debut on “Monday Night Football” and he made one small fumble.

The retired Philadelphia Eagles center officially made his appearance as an NFL analyst on ESPN’s “Monday Night Countdown,” the pre-game show for ESPN’s “Monday Night Football,” on Sept. 9.

During the introductions, host Scott Van Pelt introduced analysts Marcus Spears and Ryan Clark, as well as Kelce, discussing his outfit for the first day.

“Jason Kelce is wearing a shirt he bought at the mall because he left his duffel bag in the truck,” Spears joked.

Kelce added that the white button-up shirt “fits my stomach well now, I’ve lost a little bit of weight,” but that I was “struggling” with my chest area.

The clothing mishap came as no surprise to Kelce’s brother, Travis Kelce, who was able to joke about it.

“Surprised he bought a new one and isn’t just walking around shirtless,” Travis Kelce tweeted.

Jason Kelce is no stranger to shirtless moments. The retired football player famously went shirtless while celebrating Travis Kelce’s touchdown during the Kansas City Chiefs-Buffalo Bills playoff game in January of this year. He also went shirtless at WrestleMania 40 in April.

In another post, however, the Kansas City Chiefs tight end praised his big brother.

“What a natural talent!!” he wrote, reposting the tweet from their “New Heights” podcast with a screenshot of Jason Kelce on TV.
