Brandon Allen Fantasy Overview

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.
