In a strange game featuring two power outages and four Big Ben turnovers, the 49ers beat down the Steelers 20-3.
In the process, San Francisco moved one step closer to securing a No. 2 seed for the playoffs (while slim hopes of a No. 1 still remain).
After a blown transformer delayed kick-off 20 minutes, the Niners jumped out to a 6-0 lead behind two Roethlisberger interceptions and sustained the momentum throughout the game.
During the week, Harbaugh publicly challenged his team to "man up" after a deflating loss to the Cardinals. The players rose above the challenge and weathered everything thrown their direction, including another second quarter black-out.
The Steelers would go on to cut the lead to three, but Alex Smith responded marching the offense down the field and eventually finding Vernon Davis wide-open in the end zone for a 1-yard touchdown reception.
Huh, a redzone touchdown?
It was an early Christmas miracle on a night that belonged to the San Francisco 49ers and all their fans.
