On a cold, snowy night, the sun finally shone on the Steelers in a championship game at Heinz Field.

Safety Troy Polamalu ended a rolling Baltimore comeback when he intercepted rookie quarterback Joe Flacco's pass and returned it 40 yards for a touchdown with 4:34 left that sealed the Steelers' 23-14 victory over the Baltimore Ravens.

The victory, their first in a championship game on their third try in the past eight years at home, lifted the Steelers into their seventh Super Bowl and a chance to become the first team to win six. Their seven championships are an AFC record.

They will play against an unlikely opponent, the Arizona Cardinals, in Super Bowl XLIII in Tampa, Fla., Feb. 1. The Cardinals, often called "Pittsburgh West" because of their many connections to the city and the Steelers, will play in their first Super Bowl.
