Myles Gaskin and Boston Scott are two other running backs to consider for your weekly lineup if you are in a league that features at least 14 teams.
D'Andre Swift, Jamaal Williams, Leonard Fournette, Chris Carson, Alex Collins and Antonio Gibson are among the players who should not be in starting lineups, as the Detroit Lions, Seattle Seahawks, Tampa Bay Buccaneers and Washington Football Team get Week 9 byes.
Plenty of other running backs with great matchups this week are available aside from the elite names. Try to find a player who will get a lot of carries, targets in the passing game or goal line work and has a good Week 9 matchup.
Pittsburgh Steelers rookie Najee Harris is my No. 1 running back for Week 9. Harris scored a touchdown in three of his last four games. He also totaled at least 100 yards from scrimmage in four of his last five appearances.
This week, the Steelers battle the Chicago Bears. The Bears allowed the third-most rushing yards to running backs through eight games. Look for the Steelers to give Harris at least 30 touches in this matchup. He is a near lock for 120 yards from scrimmage and a score.
Los Angeles Chargers running back Austin Ekeler is my No. 2 option for Week 9. Ekeler is averaging the most fantasy points per game among active running backs, due to Derrick Henry's recent injury.
The Chargers star totaled at least 100 yards from scrimmage in five of his last six games. He also scored in four of his last five appearances.
The Chargers face the Philadelphia Eagles on Sunday in Philadelphia. The Eagles tied for allowing the fourth-most fantasy points per game to running backs through eight games.
I expect Ekeler to score and total at least 100 yards from scrimmage.
Miami Dolphins running back Myles Gaskin remains an inconsistent fantasy football option, but I like him as an RB2 streamer in Week 9. Gaskin, my No. 12 option, faces the Houston Texans on Sunday in Miami Gardens, Fla.
The Texans allowed a league-high 1,034 rushing yards and tied the Eagles for allowing the fourth-most fantasy points per game to running backs through eight games.
Gaskin totaled just 55 yards from scrimmage on 15 touches in Week 8, but should rebound with at least 80 yards and a score in Week 9.
Boston Scott surprised some fantasy football players with a two-touchdown performance in Week 8 for the Philadelphia Eagles. He can be used as a low-end RB2 or flex play in Week 9, when the Eagles battle the Los Angeles Chargers.
The Chargers allowed the second-most fantasy points per game to running backs through seven games. They also just allowed 80 yards and a score to New England Patriots running back Damien Harris in Week 8. I expect the Eagles to split carries, but give Scott a great chance to score again Sunday in Philadelphia.
Scott is my No. 16 option.
Veteran running back Adrian Peterson is a low-floor, high-risk option in Week 9. Peterson joined the Tennessee Titans earlier this week as a depth option due to an injury to star running back Derrick Henry.
He will likely split carries with Jeremy McNichols in Week 9, but I like his odds to score a touchdown and receive between 10 and 15 carries.
Peterson is my No. 23 option, but should only be in your lineup if you are in a league with at least 14 teams and are desperate for production at the running back position.
The Titans face the Los Angeles Rams on Sunday in Los Angeles. The Rams will likely focus on stopping the Titans pass catchers instead of the now-limited rushing attack. That should give Peterson and McNichols room to run for modest gains.
