Jason Kelce contains multitudes. The retired Philadelphia Eagles star - now a Monday Night Countdown commentator - showed off his skills on the saxophone ahead of the Baltimore Ravens-Detroit Lions showdown at M&T Bank Stadium in Baltimore. While cameras rolled during the Monday, September 22 pre-game broadcast, Jason, 37, accompanied the Ravens' marching band on a jaunty rendition of the Monday Night Football song. He sported a purple uniform and black hat, with the chin strap grazing his nose. When the song ended, he cheered and high-fived band members.
