A 30-yard completion from Brees to McCardell put the ball down on the Chiefs 30 and a 13-yard run by LaDainian Tomlinson gave the Chargers the ball inside the red zone on a drive that started at the San Diego 18. A pitch to the left to Tomlinson setup another touchdown throw from Tomlinson to a wide-open Eric Parker for a 17-yard score and 14-point lead.
For the second week in a row, Reche Caldwell fumbled the ball away after a nice catch that netted a first down deep inside Chiefs' territory. Jared Allen hit him from behind and jarred the ball loose. Larry Johnson ran around left end behind Willie Roaf after the turnover for a 46-yard run, a career-high, to put the Chiefs inside the red zone. Lawrence Tynes connected from 34 yard to get Kansas City on the board.
The Chargers executed the two-minute drill to perfection in the first half to extend their lead to 21-3. Brees hit Eric Parker twice, once for 20 yards and then for 21 yards. He then connected with Gates for 20 yards before going back to Gates for another 20 yards, which resulted in the touchdown, Gates' second of the day.
Shut out all day, Tony Gonzalez made his mark with a 36-yard grab over the middle – his longest gain of the year – and followed it up with a touchdown grab from Trent Green to cut the Chargers lead to 21-10. The drive was setup by a Green completion to Eddie Kennison for 29 yards on third-and-12, one play after Priest Holmes was knocked out of the game by Shaun Phillips.
Greg Wesley intercepted a pass from Brees and returned it 53 yards, putting the Chiefs back in business. Green hit Kennison for 33 yards to the San Diego 11 before the Shawne Merriman sacked Green and caused a fumble that Phillips pounced on to end the scoring threat.
Gates would add his third touchdown reception of the game from 35 yards out to put the Chargers up by 15. It was setup by a 31-yard kickoff return by Darren Sproles.
The Chiefs closed to within eight just before the two minute warning. Green went 6-for-6 for 69 yards with the touchdown going to Kennison.
The onsides kick from Tynes was recovered by Kassim Osgood and the Chargers killed most of the clock. The Chiefs got the ball back with 29 seconds to go but did not advance it far without timeouts and 80 yards to go.
