LaDainian Tomlinson ran in two TDs and threw for one to give San Diego its third straight comeback win. He then had 21 rushing touchdowns on the year and brought his career QB record to 7 completions out of 10 attempts with 6 touchdowns. Philip Rivers, on the other hand, struggled completing 14 of 31 passes and throwing for only a 133 yards with no touchdowns and 1 interception. The Chargers swept the Raiders and had then won seven straight from Oakland. The scoring started with the Raiders  making it 7-0 after a 1-yard pass from Aaron Brooks to Reshard Lee. The Chargers answered back when Antonio Cromartie returned the ensuing kick 91 yards, which set up a 2-yard run by LT to tie the score at 7-7 going into the half. The Raiders took the lead again on a catch and run by rookie John Madsen that set up a 2-yard pass from Brooks to Madsen to make it 14-7 Oakland.  On 4th and 2, Rivers passed to Vincent Jackson for a first down, but Jackson proceeded to get up and throw the ball forward in celebration, but he hadn't been touched down. The initial ruling was that it was a fumble and Oakland's ball; however, after the officials got together for a conference they declared that since it was an illegal forward fumble that it was technically an illegal forward pass and San Diego was then given back the ball and penalized 5 yards, which was still enough for the first down. The game continued and on the next play, Rivers pitched the ball to Tomlinson as if it were a run play but then threw the ball to an open Antonio Gates to tie the score at 14-14. After forcing Oakland to punt, the Chargers drove down field and LT ran it in from 10 yards out to give the Chargers the 21-14 win. With the win, the Chargers had won 7 straight games over the Raiders and improved their record to 9-2.
