LaDainian Tomlinson made history by becoming the fastest running back to reach 100 career TDs by doing it in 89 games, eclipsing the mark set by Emmitt Smith and Jim Brown of 93 games. He also continued his march toward beating Shaun Alexander's single-season TD record by scoring 4 TDs to bring his total to 22, just 5 short of tying Alexander's mark. Philip Rivers had a good day as well, throwing 19 of 26 for 222&#160;yards and two TDs, although he did throw two picks including a 31-yard interception return for a TD by Denver cornerback Darrent Williams. The game started out with Tomlinson running it in from 3 yards out to make it 7-0 San Diego. Denver's Mike Bell ran for two TDs in during the 2nd quarter to make it a 14-7 Denver lead at halftime. After the break, Denver continued the scoring with an Jason Elam's 42-yd field goal and Williams INT return to make it a 24-7 lead for Denver. But just like last week against the Bengals, the Chargers wouldn't say die putting together two scoring drives including a 3-yard run by LT, his 100th TD, and a 51-yd pass to LT by Rivers to cut the lead to 24-21 at the end of the third quarter. Elam helped the Broncos' cause by hitting a 38-yd kick to extend the Broncos' lead to 27-21, but that only lasted until Rivers found Vincent Jackson open at the back of the end zone to put the Chargers up 28-27. On the ensuing Broncos drive, Drayton Florence then intercepted Jake Plummer's 4th and 4 pass to give the Bolts terrific field position that set up a 1-yard run by LT to make it 35-27; it was his 4th TD of the night and 102nd of his career. That left Denver 1:14 to try to tie the game. They started that drive from their 3 and made it all the way to the Chargers 32 in part to a personal foul on Chargers defensive end Igor Olshansky, who was ejected for punching Broncos center Tom Nalen. The Broncos' hopes for overtime ended when Plummer was sacked by Shaun Phillips and time ran out, giving San Diego their first win in Denver in 7 years as well as sole position of first place in the AFC West and improved their record to 8-2.
