San Francisco 49ers quarterback Brock Purdy is expected to return to the field on Sunday against the Buffalo Bills after recovering from a shoulder

It’s not like he was throwing at game speed, but the sight of Brock Purdy throwing the ball during warmups Friday was encouraging before the 49ers left on a trip to Buffalo for a Sunday night game against the Bills.

Purdy missed the 49ers' Week 12 contest versus the Green Bay Packers last Sunday with a right shoulder injury—a game San Francisco lost 38–10. The 25-year-old was limited in practice this week on Wednesday and Thursday, and was a full participant on Friday. He's officially listed as questionable for Sunday.
