In the second quarter, New England took the lead as kicker Stephen Gostkowski got a 35-yard field goal, along with RB Kevin Faulk getting a 2-yard TD run. In the third quarter, the Patriots increased their lead with Faulk getting another 2-yard TD run.  In the fourth quarter, New England added on to its lead with Gostkowski kicking a 40-yard field goal.  The Niners tried to come back as O'Sullivan completed a 5-yard TD pass to Bruce, but the Patriots pulled away with Gostkowski nailing a 49-yard field goal.
