Mahomes and Kelce smiled as they posed with ex-NFL passer for a photo, which Christensen shared on his Instagram story. According to Christensen's story, the trio worked out at Colleyville Heritage High School in Texas. Christensen played for the Bengals, Eagles and Browns after being drafted in the fifth round of the 1983 NFL Draft.
