Knox: word is a severe sprain

49ers QB Jimmy Garoppolo is done for the season with a broken foot.

Absolutely unfortunate for Garoppolo, who helped keep the 49ers on pace for a potential Super Bowl berth after taking back the reigns from an injured Trey Lance. Now, it will be up to 2022's Mr. Irrelevant, rookie quarterback Brock Purdy, to keep the 49ers on track. Purdy went 25/37 for 210 yards, two touchdowns and one interception in San Francisco's 33-17 win over the Dolphins. Fortunately for Purdy, he gets the same talent surrounding him that Garoppolo did. How Kyle Shanahan navigates this will be very interesting to watch. But it's an unfortunate setback for Garoppolo and the 49ers, who looked primed to challenge the Eagles and Vikings in the NFC.
