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.

Lakers star Austin Reaves has been diagnosed with a mild left calf strain and will be re-evaluated in approximately one week, the team said after practice Friday.

The guard is averaging 27.8 points, 5.6 rebounds and 6.7 assists and has led the Lakers in total minutes played this season as the team weathered stretches without stars LeBron James and Luka Doncic.

Reaves responded with a career start. He is ninth in the NBA in scoring and could be on track to earn his first All-Star nod as he enters a critical contract decision this offseason.

Reaves will at least miss Sunday’s game against the Phoenix Suns, a road game at Utah on Dec. 18 and a game at the Clippers on Dec. 20.

After another road game against the Suns on Dec. 23, the Lakers begin a stretch of five consecutive home games, starting with a marquee Christmas Day matchup against the Houston Rockets.
