PHILADELPHIA -- Already down to their third-string quarterback, the San Francisco 49ers had to turn to their fourth option in the first quarter of Sunday's NFC Championship Game against the Philadelphia Eagles. And then, in the third quarter, back to their third-stringer.
Niners quarterback Brock Purdy suffered a right elbow injury on San Francisco's sixth offensive snap. After he was originally considered questionable to return, he had no choice but to reenter in the third quarter when his replacement -- fourth-string signal-caller Josh Johnson -- was ruled out with a concussion.
