49ers QB Brock Purdy (shoulder) remains uncertain for Sunday night's game vs. the Bills, according to NFL Network's Ian Rapoport. Purdy was "very limited" in Wednesday's practice, Rapoport adds. "Probably needs to improve just a little bit to be able to get on the field" against the Bills. QB Brandon Allen mustered just 199 passing yards and one TD on 6.9 yards per attempt last week and would be a big downgrade for San Francisco's offense if he starts again.

49ers QB Brock Purdy (shoulder) did some "light throwing" on Monday and felt good, HC Kyle Shanahan said. “We didn’t push him that hard,” Shanahan added. “But he did some light throwing, which was a good sign. We’ll rest him tomorrow and see how he feels as the week goes.” Two MRIs on Purdy's throwing shoulder last week -- one on Monday, one on Thursday -- revealed no structural damage. Purdy seemingly has a chance to return for Sunday night's game vs. the Bills, but we'll keep you updated on his progress throughout the week. Shanahan said QB Brandon Allen would get another start in Buffalo if Purdy is out.

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.

49ers GM John Lynch said Friday morning that QB Brock Purdy had an MRI on his right shoulder. "Feel good about where it is from that standpoint," Lynch said. But he stopped short of saying that Purdy will play vs. the Packers this weekend. "Brock will show up here today, see where he goes from practice, go forth accordingly," Lynch said. He added that QB Brandon Allen would get the start if Purdy is out but that QB Josh Dobbs would also "be ready." We'll update Purdy's status again this afternoon.
