LaDainian Tomlinson wanted to eliminate all the risks of trying a field goal in overtime.

So he took the ball, cut to his left and outran everyone on a 16-yard touchdown run with 7 1/2 minutes left in the extra period, finishing off the Chargers' rally from a 14-point fourth-quarter deficit yesterday to beat host Tennessee, 23-17.

"Anything can happen with a field goal," said Tomlinson (146 yards, 26 carries).

The Chargers (8-5) won their third straight and seventh in nine games.

"To come in here and get a win is really, really big for our guys," San Diego coach Norv Turner said. "And then the way we did it, I think the key for our football team today was we fought hard."

The Chargers won a physical game in which linebacker Shawne Merriman got two sacks early in the first half, then spent the rest of the day sidelined by an injured left knee. Tight end Antonio Gates hurt his back and returned to catch the game-tying touchdown.

Philip Rivers (21-for-40, 228 yards), intercepted twice, hurt his left knee in the first half and returned to finish the game wearing a brace.

"He went out there and gave us everything he had," Merriman said. "He wasn't 100 percent. You could see it. He was limping around all the time, still went out and fought for us."

Rivers, the Alabama native with lots of family and friends in the stands, had 37 yards passing through three quarters. He led the rally by throwing two TD passes in the final 7:29 - the last with 9 seconds left.

"He kept getting up," said Titans defensive end Kyle Vanden Bosch, who had three of Tennessee's five sacks. "He stayed after it. Especially after the fourth quarter. We knocked him down a couple times. I had him wrapped up once and he was able to get the pass off. He showed a lot of resolve at the end of the game."

Tennessee (7-6) had a chance to run out the clock in a game the Titans desperately needed to stay close to Cleveland and Jacksonville in the chase for the AFC's two wild-card berths. But they gave the ball back to San Diego with 2:24 left in regulation, then went three-and-out in overtime.

The loss wasted a strong performance by the Tennessee defense, which had three interceptions. But the Titans couldn't get close enough to Rivers when it mattered as he tossed a 7-yard TD to Tomlinson with 7:29 left to cap a 92-second drive.

"It was as physical a game as I've been in," Rivers said. "That's the way it goes. I didn't feel like I was running for my life."
