Houston

The Chargers have never won five in a row under coach Jim Harbaugh, but they have a chance to do so Saturday. It won’t be easy against this Houston Texans defense, ranked No. 1 in the NFL.

The Texans crushed the Chargers in the first round of the playoffs last season, intercepting Justin Herbert four times in a 32-12 drubbing.

Now, the Texans are riding a seven-game winning streak and haven’t dropped a game since a three-point home loss to Denver at the beginning of November.

The Chargers clinched a playoff berth this week but are looking for more than a wild-card spot. If they win Saturday, the AFC West title — and at least one more game at SoFi Stadium — is within reach. Even the AFC’s No. 1 seed is in play.

How the Texans can win: Houston’s defense can hold up against the run and has the secondary to challenge Herbert, but the Texans offense has been one of the league’s worst in the red zone. The Texans need to convert those opportunities into touchdowns. C.J. Stroud is at his best throwing between the numbers when protection holds, although he has a suspect offensive line, and the Texans will lean on short passes to compensate for a shaky running game. Forcing a turnover or two is critical. Houston thrives when it shortens the field and avoids asking the offense to sustain long drives. Field goals alone won’t be enough.

How the Chargers can win: Control the game with balance and patience. Houston’s defense is opportunistic and excellent at forcing turnovers, but it can be stressed if Herbert has time and the Chargers stay committed to the run. That won’t be easy if Kimani Vidal is out. Even modest success on the ground forces the Texans to respect play-action fakes and opens throwing lanes, particularly over the middle. Herbert’s ability to escape pressure and run, especially up the middle against man coverage, could be a hidden weapon late. If the Chargers protect the ball and finish drives instead of settling for field goals, they can keep Houston from dictating the tempo.

ARLINGTON, Texas — The Chargers won Sunday, and now they wait.

After their 34-17 victory over the Dallas Cowboys on Sunday, the Chargers can secure a spot in the postseason with a loss or tie by Houston or Indianapolis.

The Texans play host to Las Vegas in an afternoon game, and the Colts play host to San Francisco on Monday night.

It was the seventh win in eight games for the Chargers, who are on a season-long, four-game winning streak. Sunday marked the third time they have topped 30 points this season.

Chargers quarterback Justin Herbert turned in another gritty performance, throwing for two touchdowns and plunging over the goal line for a third.

A pivotal play by Herbert came on third-and-seven early in the fourth quarter, he kept the ball and scrambled for 34 yards. At the end of that run, his surgically repaired left hand collided with the helmet of his Cowboys tackler. The quarterback briefly writhed on the turf, but didn’t come out of the game.

Late in the game, as rookie Omarion Hampton ran for a touchdown, Herbert joined him in the end zone and exchanged high-fives with teammates, careful to protect his casted left hand.

Although the Cowboys came into Sunday’s game eliminated from postseason contention, they still had the NFL’s No. 1 offense and a potent passing attack led by Dak Prescott. He effectively neutralized the Chargers defense in the first half, with touchdown passes in the first and second quarters.

The Chargers close the regular season with a home game Saturday against Houston and a finale at Denver.
