The network had no immediate comment Monday on the complaint.
CBS has said it was airing the pregame, postgame and halftime portions of the show on tape delay to guard against the use of bad language or wardrobe malfunctions. The postgame delay does not begin until the first block of commercials after the game, which hadn't happened before Flacco's expletive.
CBS' Craig Ferguson was quick to poke fun at the power outage on his comedy show, which aired after "Elementary." He was shown plugging actress Lucy Liu's cellphone charger into a power outlet at the Superdome, despite instructions not to use it.
"It's one outlet," Ferguson said. "What could possibly go wrong?"
The picture switched to the lights going out in half the dome.
