Coming off their bye week, the Bills played a Week 7 duel with the San Diego Chargers.  In the first quarter, Buffalo drew first blood as kicker Rian Lindell got a 38-yard field goal.  The Chargers responded with QB Philip Rivers completing a 14-yard TD pass to WR Malcom Floyd.  In the second quarter, the Bills regained the lead with QB Trent Edwards (fully recovered from his concussion) completing a 2-yard TD pass to WR Lee Evans, along with Lindell getting a 27-yard field goal. In the third quarter, San Diego regained the lead with Rivers completing a 12-yard TD pass to WR Vincent Jackson.  Buffalo answered with RB Marshawn Lynch getting a 9-yard TD run.  In the fourth quarter, the Bills pulled away with Lindell nailing a 44-yard field goal. With the win, not only did Buffalo improve to 5-1, they also got their first 3-0 home start since 1995. A power outage at Ralph Wilson Stadium, caused by three helium balloons coming in contact with a transformer, led to portions of the game not being televised. For a short time during the first and second quarters, the game was played with no public address announcers, no scoreboard, and the time was kept by the officials on the field.
