Brock Purdy Out For Week 12

49ers QB Brock Purdy (shoulder) is out for Sunday's game vs. the Packers. His injured right shoulder evidently didn't progress throughout the week as the team had hoped. GM John Lynch said Friday that an MRI on the shoulder didn't show anything concerning, so we're not expecting this to be a long-term absence. But Purdy's absence this weekend leaves QB Brandon Allen as San Francisco's expected starter. Allen has been with the 'Niners since May 2023 but has not attempted a regular-season pass for them. He completed just 57% of his passes at 6.1 yards per attempt in limited action for the Broncos and Bengals from 2019-2022. Allen is clearly a significant downgrade for all San Francisco pass catchers. Expect the team to lean heavily on RB Christian McCaffrey on Sunday.
