Watch Tennessee Titans vs San Diego Chargers Live Online - NFL Wild Card Weekend Preview

For the second straight season, the San Diego Chargers are on a roll heading into the playoffs. This time around, they're trying not to be overconfident, especially with a matchup against a Tennessee Titans team that is thrilled to be getting another crack at the AFC West champions.

San Diego brings another long winning streak into the postseason on Sunday when it meets visiting Tennessee for the second time in five weeks.

The first matchup between these teams resulted in a 23-17 overtime victory for San Diego in Nashville on Dec. 9 -- the Titans' only loss in their last five games.

In that contest, the Chargers (11-5) rallied from 14 points down in the fourth quarter, tying the game at 17 on a 2-yard touchdown pass from Philip Rivers to tight end Antonio Gates with 9 seconds remaining. San Diego won on LaDainian Tomlinson's 16-yard TD run in overtime.

The game was extremely physical, with four players getting fined a total of $32,500 by the NFL and Chargers linebacker Shawne Merriman accusing the Titans of a cheap shot that left him with an injured knee.

"I know that there's a lot of things that went on a few weeks ago when we played them at our place, a lot of bad blood in this game," said Tennessee center Kevin Mawae, who was docked $5,000 for a hit on Merriman. "So it'll be interesting to see. We're going to try to stay focused this week and not get caught up in the locker room trash talk and just focus on ourselves.

"We go out to San Diego and give them our best shot."

Tennessee (10-6) is still upset about the last meeting, believing it was on the wrong end of a call on a crucial fourth-and-5 play for San Diego during the final drive of regulation. Rivers threw a pass downfield to Chris Chambers, who had to dive back for the ball, and the officials ruled it a catch.

It was replayed because it came in the last two minutes, but not overturned because of a lack of camera angles.

"If people missed the first one that we played, tune in," Titans linebacker Keith Bulluck said.

Rivers, though, isn't ready to label this wild-card game as a grudge match.

"Nah, I mean, we won the game. That's all that matters to us," he said. "It's a new game now. We get to play them at home. It's going to be another fun, physical game. I'm looking forward to it."
