Brock Purdy bounced back from the worst game of his NFL career to throw two touchdown passes, and the 49ers clinched the top seed in the NFC by beating the Washington Commanders, 27-10, Sunday in Landover, Md.

Philadelphia’s stunning home loss to Arizona, combined with Detroit’s defeat at Dallas Saturday, allowed the 49ers (12-4) to sure up a first-round bye and home-field advantage before Week 18. A large cheer erupted from the visiting locker room when the Eagles lost.

Washington (4-12) wasn’t much of an obstacle for San Francisco, whose only concern coming out of the victory could be the status of do-it-all running back Christian McCaffrey (calf), who had 91 scrimmage yards on 18 touches.
