The San Francisco 49ers have battled injuries to some of their best weapons this season, and that trend continued this week, with quarterback Brock Purdy nursing a shoulder issue ahead of Week 12. 49ers head coach Kyle Shanahan announced Friday that Brandon Allen will start in place of Purdy for Sunday's game against the Packers.

Allen became a 49er on May 8, 2023, signing as a free agent. The 49ers, who up to that point seldom kept a third quarterback on the 53-man roster, kept Allen as a No. 3 all season behind Purdy and Sam Darnold after the previous year’s injuries to Trey Lance, Jimmy Garoppolo, and finally Purdy in the NFC Championship Game. Allen did not take a snap.
