SAN DIEGO — Philip Rivers had a touchdown pass and Nick Novak added two field goals as the San Diego Chargers defeated the Oakland Raiders, 13-6, on Sunday.

The Chargers (6-4) handed the Raiders (0-10) their 16th consecutive loss and San Diego put an end to its own three-game losing streak.

Oakland, which has gone a calendar year without a win, never led the game but kept it interesting to the final minute.

Rivers connected with wide receiver Malcom Floyd for a 22-yard touchdown early in the first quarter and Oakland never mounted a serious threat.

Rivers (22 of 34 for 193 yards and a touchdown) wasn’t sharp. The Chargers’ struggling offense — one touchdown in two games — neglected to take advantage of numerous Oakland mistakes but welcomed back running back Ryan Mathews. He led the team with 70 yards on 16 carries in his first game since the Chargers beat Seattle in Week 2.

Raiders quarterback Derek Carr completed 16 of 34 attempts for 172 yards. The Raiders scored on two Sebastian Janikowski field goals.

In the third quarter, Novak kicked a 52-yard field goal for a 13-3 Chargers’ edge.

But that series came with some anxious moments. Rivers was hobbled after getting hit on a pass attempt but stayed in the game and limped in and out of the huddle for the rest of the game.

It appeared the Chargers would add to their cushion in the final minute of the first half.

The Chargers reached the Raiders’ 20 with a timeout. But Rivers failed to get a play off before finally stopping the clock for a 48-yard Novak field-goal attempt.

But Novak was wide left, snapping his franchise record of 32 straight field goals.

The Chargers extended their advantage to 10-3 on Novak’s 23-yard field goal. The Chargers had a first down at the Oakland 9, but two Braden Oliver runs and a Rivers incomplete force San Diego to settle for a field goal.

Janikowski’s 42-yard field goal midway through the first quarter cut the Chargers lead to 7-3.

The Raiders never did look comfortable.

On the game’s first snap, Carr wasn’t ready for the snap and the ball ricocheted off him. Chargers linebacker Donald Butler recovered the fumble and the Charger took over on Oakland’s 22-yard line.

Rivers quickly converted the game’s lone turnover when finding Floyd in single coverage for a 22-yard scoring pass.
