Trying to rebound from their MNF divisional road loss to the Titans, the Colts went home for a Week 9 Sunday night duel with their hated rival, the New England Patriots.  In the first quarter, Indianapolis got off to a fast start as QB Peyton Manning completed a 12-yard TD pass to WR Anthony Gonzalez.  In the second quarter, the Patriots responded as kicker Stephen Gostkowski got a 29-yard and a 35-yard field goal.  In the third quarter, New England took the lead as RB BenJarvus Green-Ellis got a 6-yard TD run (with a failed 2-point conversion).  The Colts would answer with Manning hooking up with Gonzalez again on a 9-yard TD pass, along with completing a 2-point conversion pass to WR Reggie Wayne.  In the fourth quarter, the Patriots tied the game with Gostkowski getting a 25-yard field goal, yet Indy replied with former Patriot kicker Adam Vinatieri nailing a 52-yard field goal.  Afterwards, Indianapolis's defense prevented New England's last attempt at a comeback.
