NEW ORLEANS —
"The bad part was we started talking about it," said safety Ed Reed, who had the game's only interception. "That was mentioned. It was like they were trying to kill our momentum."
After power was restored, the 49ers began playing lights out.
San Francisco (13-5-1), in search of its sixth Lombardi Trophy in as many tries, got back in the game almost immediately.
Michael Crabtree's 31-yard touchdown reception, on which he broke two tackles, made it 28-13. A few minutes later, Frank Gore's 6-yard run followed a 32-yard punt return by Ted Ginn Jr., and the 49ers were within eight.
Ray Rice's fumble at his 24 led to David Akers' 34-yard field goal, but Baltimore woke up for a long drive leading to rookie Justin Tucker's 19-yard field goal.
San Francisco wasn't done challenging, though, and Kaepernick's 15-yard TD run, the longest for a quarterback in aSuper Bowl, made it 31-29. A 2-point conversion pass failed when the Ravens blitzed.
Tucker added a 38-yarder with 4:19 remaining, setting up the frantic finish.
Kaepernick couldn't get the 49ers into the end zone on the final three plays. The last was a pass into the right corner of the end zone to Crabtree that involved some incidental bumping. Jim Harbaugh insisted a flag should have been thrown.
"There's no question in my mind that there was a pass interference and then a hold," Jim Harbaugh said.
Ravens punter Sam Koch took a safety for the final score with 4 seconds left. Koch's free kick was returned by Ginn to midfield as time ran out.
"How could it be any other way? It's never pretty. It's never perfect. But it's us," John Harbaugh said of his Ravens. "It was us today."
