Purdy came away from the season-opening win against the Seattle Seahawks with toe and left shoulder injuries, his toe being the bigger concern. San Francisco coach Kyle Shanahan said earlier in the week that he did not expect Purdy to play but left the door ajar. Jennings had been questionable due to ankle and shoulder injuries. Against the Saints, he caught five passes for 89 yards and a touchdown.
