Not every high-profile player listed as questionable this weekend is a lock to play. Per a source with knowledge of the situation, Chargers tight end Antonio Gates, officially questionable with a foot injury, will not play against the Chiefs.

Gates did not practice on Wednesday, Thursday, or Friday.

The “questionable” designation literally means that the player’s availability is a 50-50 proposition. For Gates, it’s currently more like zero.

Gates missed six games last season due to injury. Before that, he had played four full seasons without missing a single game. Through the first seven years of his career, Gates played in all but three games.
