The Chiefs haven't won a playoff game in 20 years, but they definitely had a chance to break that streak with offensive powerhouse Jamaal Charles at their side. So imagine the disappointment of the fan base when the running back left early in the first quarter with an injury.

Charles stayed down on the field after a clean tackle and was seen going through some concussion tests right after. The running back walked into the locker room a few minutes later. That's bad news for the Chiefs, because Charles accounted for over a third of their offense this season.

UPDATE: Charles is definitely out of the game with a concussion.
