While it was made clear that it isn't a serious injury, Chiefs coach Andy Reid said quarterback Alex Smith suffered a shoulder sprain during the Chiefs 34-7 victory over the St. Louis Rams on Sunday.
"Alex has a shoulder sprain," Reid said during Monday's press conference. "He was obviously able to go through the game and everything worked out okay, but he was a bit sore today."
Smith finished the game 24 of 28 for 226 yards.
The 85.7 completion percentage for Smith on Sunday ranks best in Chiefs history, a record Smith set last season against the Oakland Raiders on December 15, when he went 17 of 20 (85 percent).
Reid said he believes the injury happened late in the first half.
"I believe it happened right before halftime," Reid said. "He just kind of landed on it. It's probably more of a bruise than anything but it's pretty tender."
Smith went 10 of 13 for 115 yards in the second half and didn't have to worry about throwing the ball when the Chiefs got the ball right after halftime because Knile Davis took it back 99 yards for the touchdown on the opening kickoff.
While Reid didn't seem worried about the injury in any way, it's still something to monitor this week as the Chiefs prepare for the New York Jets, whom they host next Sunday.
