He left the game limping to the sideline early in the 4th quarter. Nazeeh Johnson will likely take over the starting role in Watson's absence. Reid spoke highly of his capabilities. Smith-Schuster was questionable with a hamstring injury going into the game against the 49ers. He decided to try and play but went down while running a route during the first quarter.
