Brock Purdy remained limited in a Thanksgiving Day practice, keeping his status in doubt for the 49ers’ game Sunday at Buffalo.
Purdy missed last Sunday’s 38-10 loss at Green Bay because of a shoulder injury that’s disabled his throwing ability since the previous game’s loss to Seattle.
Brandon Allen started in place of Purdy for the 49ers (5-6) in the loss at Lambeau Field. The Bills (9-2) took a six-game win streak into their bye last weekend.
Also not practicing Thursday were defensive end Nick Bosa (oblique, hip), left tackle Trent Williams (ankle), guard Aaron Banks (concussion), cornerback Deommdore Lenoir (knee), defensive tackle Jordan Elliott (concussion) and linebacker Demetrius Flannigan-Fowles .
Thursday’s practice was held without media access so there was no indication what level of workload Purdy was cleared to attempt.
