It turns out Cassel has more than that. Cassel has a rib injury that could prevent him from playing in Sunday’s regular season opener against Buffalo at Arrowhead Stadium.

Head coach Todd Haley reportedly told backup QB Tyler Palko, "You'd better be ready to play Sunday."

The Packers 340-pound defensive lineman Howard Green crushed into Cassel during the 4th pre-season game where Todd Haley decided to play some of his starters late into the 4th quarter.

During that game the Chiefs also lost TE Tony Moeki for the season with an ACL tear.
