The Steelers' ninth game was an AFC duel with the Patriots. The Steelers trailed early as QB Tom Brady made a 19-yard TD pass to TE Rob Gronkowski. This was followed by kicker Shayne Graham getting a 31-yard field goal. The Steelers responded in the second quarter with kicker Jeff Reed nailing a 22-yard field goal. The Steelers struggled further when Brady threw another TD pass to Gronkowski, this one from 9&#160;yards out. That was followed by Brady's scramble 3&#160;yards to the endzone for a touchdown (With a failed PAT as the kick went wide-right). The Steelers scored first in the 4th quarter when QB Ben Roethlisberger completed a 6-yard TD pass to WR Emmanuel Sanders. The Steelers looked to create another scoring drive, but it came to a halt when Roethlisberger's pass was intercepted by SS James Sanders and returned 32&#160;yards for a touchdown (With a failed 2-point conversion). The Steelers tried to cut the lead with a Roethlisberger 15-yard TD pass to WR Mike Wallace, but the Patriots replied with Brady getting a 25-yard TD pass to Gronkowski. Again the Steelers tried to get closer when Roethlisberger completed a 33-yard TD pass to Wallace, but the Patriots put the game away after Graham hit a 36-yard field goal.
