SANTA CLARA — There was no Jimmy G on Thursday night, but Nick M did just fine against the hapless Raiders.
Nick Mullens — the 49ers’ undrafted, unknown third-string quarterback — took pity on a cynical prime-time audience by providing a performance worth watching in his NFL debut.
Subbing for the injured C.J. Beathard (wrist), who had been subbing for the injured Jimmy Garoppolo (knee), the kid from Southern Mississippi did what pretty much every other quarterback has done this season: He carved up a Raiders defense that barely seems to care.
Mullens completed 16 of 22 passes for 260 yards and three touchdowns to lead the 49ers’ 34-3 victory.
