When your starting quarterback goes down with an injury, it's comforting to have an experienced backup who is ready to play.
This is the situation the Kansas City Chiefs find themselves in after Alex Smith left the game against the Indianapolis Colts in Week 8. He was replaced by Nick Foles, who has spent parts of four seasons as a starter in the NFL.
According to Jason La Canfora of CBSSports.com, Foles will start the team's Week 9 game while Smith remains sidelined, though the Chiefs have maintained that Smith didn't suffer a concussion.
