After being checked for a concussion in the first half of Sunday's game against the Indianapolis Colts, Alex Smith returned to the game. Unfortunately for the Kansas City Chiefs, Smith later suffered another blow to the head. This time, the veteran quarterback had to exit with a concussion. He was not able to return. Couple that with the concussion Spencer Ware suffered, and Sunday's game may have come with a price for Kansas City. If Smith is unable to go next week, Nick Foles will get the start.
