Answer based on context:

Hoping to rebound from their road loss to the Dolphins, the Chargers went home, donned their alternate uniforms, and played a Week 6 Sunday night duel with the New England Patriots, in a rematch of last year's AFC Championship game. In the first quarter, the 'Bolts struck first as kicker Nate Kaeding got a 25-yard field goal, along with QB Philip Rivers completing a 49-yard TD pass to WR Malcom Floyd.  In the second quarter, the Patriots got on the board as kicker Stephen Gostkowski got a 47-yard field goal.  San Diego closed out the half with Rivers completing a 4-yard TD pass to WR Vincent Jackson. In the third quarter, the Chargers continued its victory march as Rivers completed a 1-yard TD pass to TE Antonio Gates, along with Kaeding kicking a 35-yard field goal.  In the fourth quarter, the 'Bolts closed out the night with Kaeding nailing a 35-yard field goal.  New England would respond with RB Sammy Morris getting a 1-yard TD run, yet San Diego was too much for them.
