The Ravens were almost done in Sunday by a reign delay.

A power outage at the Superdome halted Super Bowl XLVII for 34 minutes casting the stadium into a twilight-like darkness and allowing the reeling 49ers to regroup with almost a full half remaining.

Despite an impressive power surge by the 49ers, however, the Ravens were able to hang on for a 34-31 victory, hoisting the Lombardi Trophy for the second time in their history.

"It's never pretty, it's never perfect, but it's us," said Ravens coach John Harbaugh, whose team had lost four of its last five regular-season games before going on a marvelous run that included knocking off the Colts, Broncos and Patriots to reach the biggest stage.

Even before the ball was kicked off, the game made history. For the first time, brothers stood on opposite sidelines as head coaches. John's younger brother, Jim, coaches the 49ers, making Sunday's victory somewhat bittersweet for the Ravens coach.

"It's tough," John said. "It's very tough. It's a lot tougher than I thought it was going to be. It's very painful."

Most excruciating for the 49ers was how close they came. The game essentially ended on a goal-line stand, with three incomplete passes by the 49ers from the Ravens' 5 inside the final two minutes.

Second-year quarterback Colin Kaepernick, who showed incredible poise for a player with just 10 career starts, failed to connect with Michael Crabtree on three straight tries. On the last, Jim Harbaugh complained angrily that cornerback Jimmy Smith had held Crabtree, but officials were unsympathetic.

"There's no question in my mind that there was a pass interference and then a hold on Crabtree on the last one," the 49ers coach said.
