Following their Monday Night at Miami, the Patriots returned to Foxborough for their home opener against the San Diego Chargers. In the first quarter, Patriots' quarterback Tom Brady threw a 14-yard touchdown pass to tight end Aaron Hernandez, but the Chargers responded, with a 10-yard touchdown run by running back Ryan Mathews. The Patriots scored 13 unanswered points in the second quarter, with a 22-yard field goal by placekicker Stephen Gostkowski, a 10-yard touchdown pass from Brady to tight end Rob Gronkowski, followed by a 47-yard field goal by Gostkowski just before halftime. After a scoreless third quarter, the Chargers cut into the Patriots lead, with a 3-yard touchdown pass from quarterback Philip Rivers to wide receiver Vincent Jackson. The Patriots responded, with Brady throwing a 17-yard touchdown pass to Rob Gronkowski (and a two-point conversion run by running back Danny Woodhead). The Chargers tried to rally, with Rivers throwing a 26-yard touchdown pass to Jackson, but a 16-yard touchdown run by Patriots' running back BenJarvus Green-Ellis just after the two-minute warning sealed the win for New England.
