The game between the Pittsburgh Steelers and San Francisco 49ers  was delayed twice because of a pair of power outages at Candlestick Park.

The first outage Monday night pushed back the opening kickoff by 20 minutes. The second delay came early in the second quarter and halted the game for about 15 minutes.

The lights are back on at Candlestick Park and the game has resumed.

The 49ers lead the Steelers 6-0 in a matchup of first-place teams.
