The Facts: Purdy stayed healthy until he didn’t, with a serious elbow injury in the NFC Championship game resulting in offseason surgery. He’s working his way back, and his head coach is happy with what he has seen so far in camp. “I think he’s done great,” Kyle Shanahan told reporters on Sunday. “He has come back. He’s had no arm troubles. He’s been totally healthy. I think he’s getting all his timing back, his rhythm. I was really impressed with him in his two practices.”

And now he’s working to get ready for Week One, and to resume his status as the team’s unlikely starting quarterback.
