The 49ers turned back to Jimmy Garoppolo earlier this season after Trey Lance suffered a season-ending ankle injury. Now, they are turning to rookie Brock Purdy after Jimmy G suffered his own ankle injury vs Dolphins.
The injury happened after Jimmy G was sacked, who was immediately favoring his lower body not he sidelines. After visiting the medical tent, Garoppolo was carted to the locker room and ruled out for the remainder of the game:
Would be a pretty significant loss and change the landscape of the NFC West if Jimmy G is out for a significant amount of time.
