It was the first playoff win for the Chargers since 1994, when San Diego went to the Super Bowl.
But Tennessee made the Chargers earn the victory, taking a 6-0 lead into the half behind two Rob Bironas field goals. San Diego didn't take the lead until the 2:35 mark of the third quarter, when Philip Rivers found Vincent Jackson from 25 yards out for a 10-6 lead.

San Diego added to the lead in the fourth quarter when LaDainian Tomlinson scored on a one-yard run to establish the final score.
Because the Chargers, the No. 3 seed in the AFC, won, that means No. 5 seed Jacksonville travels to New England for a shot at the unbeaten Patriots in the other divisional round AFC matchup. In the NFC, Seattle defeated Washington, 35-14, while the New York Giants downed Tampa Bay, 24-14.
That sets up a trip to No. 1 seed Dallas for New York, while Seattle will visit Green Bay in the other NFC matchup.
In Indianapolis, the Colts will look to avenge one of their two regular-season losses when they take on the Chargers. San Diego defeated the Colts, 23-21, on Nov. 11 in San Diego.
The Colts will have to improve in three areas if they hope to avoid a similar fate this weekend. In the first game, quarterback Peyton Manning threw a career-high six interceptions, the special teams allowed two returns for touchdowns and Adam Vinatieri missed a short field goal that would have won the game in the final seconds.
