SAN DIEGO - Philip Rivers threw a 22-yard touchdown pass to Malcom Floyd on the game's third play from scrimmage, and the San Diego Chargers held on for a lackluster 13-6 victory against winless Oakland on Sunday, extending the Raiders' losing streak to 16.
Rivers hurt his right leg midway through the third quarter but stayed in the game. The injury appeared to get progressively worse, and Rivers was walking gingerly on the sideline in the fourth as backup Kellen Clemens warmed up.
Rivers went back in after Sebastian Janikowski kicked a 25-yard field goal to pull the Raiders within a touchdown with four minutes to play.
The Chargers (6-4) snapped a three-game losing streak and welcomed back Ryan Mathews, Manti Te'o and Melvin Ingram, who had been out since September.
The skid by the Raiders (0-10) is the equivalent of a full season. Monday is the one-year anniversary of their last win, 28-23 at Houston.
Rivers was hurt after a 28-yard completion to Floyd was negated by a holding call against left tackle King Dunlap. The Chargers had to settle for Nick Novak's 52-yard field goal that made it 13-3.
Oakland got to the San Diego 7 with 4:10 left, but the drive stalled and Janikowski kicked his 25-yarder.
The Chargers were coming off their bye, which was preceded by a 37-0 loss at Miami on Nov. 2, their worst in 18 seasons.
Novak extended his franchise-record streak to 32 consecutive field goals by making a 23-yarder late in the second quarter. He then pushed a 48-yard attempt wide left as the second quarter ended.
Raiders rookie Derek Carr fumbled on the game's first play from scrimmage when he mishandled a shotgun snap, and San Diego linebacker Donald Butler recovered at the 22. Two plays later, Floyd leaped to catch a touchdown pass over T.J. Carrie.
Carr almost led the Raiders to an upset of the Chargers on Oct. 12 but was intercepted with 1:13 to play by rookie Jason Verrett to preserve San Diego's 31-28 victory. Verrett is out for the season with a shoulder injury.
The Raiders crossed the 50-yard line only twice Sunday. They got to the San Diego 23 on their third drive before settling for Janikowski's 42-yard field goal.
Rivers was 22 of 34 for 193 yards. Carr was 16 of 34 for 172 yards.
A desperation pass by Carr fell incomplete short of the end zone as time expired.
