Before The Kansas City Chiefs and Philadelphia Eagles faced off on Sunday, September 14, retired NFL player Jason Kelce took one look at the pregame fashion and threw a flag on the play. Jason, 37, posted a video of his brother, Chiefs tight end Travis Kelce, arriving in style alongside a photo of Eagles wide receiver DeVonta Smith rolling up to the stadium on Sunday. "Looks like we're having ourselves a good old fashioned suit shorts battle this evening," Jason wrote via X, poking fun at their style showdown.
