Jason Kelce is what Jason Kelce does.

The former Philadelphia Eagles center played for his Monday evening countdown debut for the San Francisco 49ers-New York Jets season opener, and it went pretty much as expected. Kelce dropped a NSFW comment on the radio, while his brother, Travis, proudly watched him on TV à la the Leonardo DiCaprio meme.

In a night of firsts, Kelce was also told for the first time that he was wrong as an analyst. Joining a panel with ESPN’s Ryan Clark and others, Kelce spoke at length about how the absence of Christian McCaffrey was a huge blow to the 49ers. Only to watch backup running back Jordan Mason seamlessly step into McCaffrey’s RB1 role, rushing for 147 yards and a touchdown in San Francisco’s 32-19 win.

Kelce was the first to make a fool of himself shortly after the game ended.

He wrote on X (formerly known as Twitter): “Well this is about as well aged as warm milk.”

Chances are this won’t be the only time Kelce takes back his words.
