Prior to kickoff, the game was delayed due to the turf being caught on fire, coming from the fireworks. The Rams struggled offensively and defensively all game long.  The defense, for the most part, sacked Ben Roethlisberger until he left the game with an apparent knee injury. Michael Vick took over for the rest of the game. Late in the fourth quarter Kenny Britt's catch was overturned. The Steelers would go on to stun the Rams, 12-6.. Whose defense was disappointing?
