The Rams are still looking for a No. 2 running back to emerge behind Steven Jackson
Chris Ogbonnaya has averaged 1.2 yards per carry, rookie Keith Toston has averaged 2.3 yards per carry and Kenneth Darby has averaged 3.1 yards per carry in the preseason.
"I think Kenny Darby played a little bit better last week," head coach Steve Spagnuolo said. "Oby' has done some good things, a good third-down back, but somebody has to surface there so in the -- knock on wood -- event that we need a running back we'll have somebody to go (in)."
