KANSAS CITY, Mo. (AP) — Chiefs quarterback Alex Smith played through a sprained throwing shoulder that he sustained just before halftime of Sunday’s 34-7 rout of the St. Louis Rams. Smith never mentioned the injury in his postgame remarks, and it wasn’t until Chiefs coach Andy Reid brought it up Monday that anybody learned of it outside the Kansas City locker room.

Reid said that Smith landed on his shoulder but played through the pain. The game was still very much in the balance when the injury happened, the Chiefs leading just 10-7 at the break. Smith went through a series of examinations Monday. Reid said the quarterback is “tender” and declined to say whether he will miss any practice time this week.

The Chiefs play the New York Jets on Sunday.
