The lights go out twice during Monday night's game between the Steelers and 49ers, who won 20-3, after sitting through two delays.
SAN FRANCISCO — Monday Night Football nearly became a Monday Night Fiasco.
San Francisco's lights-out return to prime time helped salvage what could have been an embarrassing night for everyone involved on the NFL's biggest stage after a pair of power outages delayed the game for close to 35 minutes in all.
The 49ers rode their top-ranked run defense once again to beat ailing quarterback Ben Roethlisberger and the Pittsburgh Steelers 20-3 on Monday night.
Vernon Davis caught a 1-yard touchdown pass for the 49ers (11-3) one play after setting himself up with a 21-yard reception from Alex Smith, Frank Gore ran for a 5-yard score and David Akers kicked field goals of 22 and 38 yards to overtake Hall of Famer Jerry Rice for San Francisco's single-season scoring record.
The Steelers (10-4) missed a key chance to take sole possession of first place in the AFC North and gain the AFC's No. 1 playoff seed.
"I think we showed the world we can play the game of football on a national stage," Davis said. "At the end of the day that's what it's all about: respect."
Roethlisberger, playing on a sprained left ankle that had Big Ben in a walking boot during the week, threw two early interceptions and another in the waning minutes.
Even all those Terrible Towel-waving Steelers supporters couldn't will their team when San Francisco's unique home-field advantage became two blackout delays.
San Francisco became the first team in NFL history to hold an opponent without a rushing touchdown through each of the first 14 games.
Roethlisberger still finished 25 for 44 for 330 yards, but was sacked three times. After his second pick, he fumed as he limped off the field and could be seen yelling into his chin strap.
The 49ers made a big statement in their most meaningful home game since their last trip to the playoffs in January 2003, when San Francisco came from behind to stun the New York Giants 39-38 in one of the greatest comebacks in NFL history.
They had to wait 20 minutes to get started after the power went out the first time. It didn't seem to faze San Francisco.
Smith wasn't sacked after being taken down 18 times in the previous three games, including nine in the Niners' prime time flop at Baltimore on Thanksgiving night against Jim Harbaugh's big brother, John.
Jim Harbaugh prepared for the Steelers by comparing notes with his brother after the Ravens won both meetings this season with Pittsburgh in one of the AFC's fiercest rivalries.
The 37-year-old Akers, who long admired Rice from afar growing up in Kentucky, topped Rice's 138 points scored in 1987.
Yet Akers has said he doesn't feel deserving of the points mark over a great such as Rice — who clowned around on the field before the game catching passes from fellow Hall of Famer and former QB Steve Young, including one in the end zone.
It was after Akers' second field goal when everything went dark for a second time. Thousands of flashbulbs went off in the midst of the black, with a sellout crowd of 69,732 sitting in darkness — including all those Steelers fans who travel the country with their team.
NFL security chief Jeff Miller said he witnessed a transformer blow up while he was monitoring a gate outside the stadium, where a shooting during the preseason already put a negative light on this venue.
The second delay came early in the second quarter and halted the game again between the playoff-bound teams for about 15 minutes. Miller and other NFL officials gathered in the press box to assess the situation, remaining in constant contact with the commissioner's office.
This was the 49ers' only Monday Night game this season and their final regular-season home game at Candlestick Park. The NFL certainly will want to make sure there are no problems when San Francisco hosts a home playoff game next month as NFC West champions — and Miller said he remains confident Candlestick can capably host a playoff game.
The Steelers missed linebacker James Harrison, who served his one-game suspension for a helmet to facemask hit on Browns quarterback Colt McCoy on Dec. 8.
This marked the fourth time in Monday Night Football history that two teams faced off with 10 victories and a winning percentage of at least .750 — and San Francisco has played in all of them, the last on Dec. 15, 1997, with the 12-2 49ers vs. 11-3 Broncos.
