Nick Mullens’ debut is verifiably good in 49ers’ 34-3 romp over Raiders

Nick Mullens, in his first NFL game, was the story of the final Battle of the Bay.

The 49ers’ third-string quarterback entered a prime-stage Thursday in anonymity and he exited with a stat line befitting his Hall-of-Fame buddy, Brett Favre, who gave a him a congratulatory postgame phone call when Mullens was on the NFL Network set.

Mullens, a 2017 undrafted free agent from Favre’s alma mater, Southern Miss, completed 16 of 22 passes for 262 yards and three touchdowns in a 34-3 pounding of the Raiders at Levi’s Stadium. His 151.9 passer rating was the best by a QB in his first start with at least 20 attempts since the NFL-AFL merger in 1970, according to ESPN.
