Rams running back Benny Cunningham was the team's primary backup in Week 9 against the Titans, after missing the two previous games with an ankle injury.
Cunningham received just three carries and finished the game with 11 yards, and had no impact on the passing game. He also lost a fumble in the red zone on the team's first drive.
As long as Daryl Richardson is out, Cunningham will be the team's No. 2 back. However, he will likely continue to have a limited role. The Rams face the Colts in Week 10.
