Steven Jackson does not dress for Rams' preseason finale

Steven Jackson sat out St. Louis' preseason finale against the Baltimore Ravens on Thursday night, giving the Rams more time to find a backup running back.

Backup quarterback A.J. Feeley also was out for the second straight game because of a sprained right thumb.

Jackson, who participated in pregame warmups, finished the preseason with nine carries for 42 yards. Earlier in the week, coach Steve Spagnuolo said it was 50-50 whether Jackson would play, perhaps to develop chemistry with No. 1 pick Sam Bradford.

Kenneth Darby, Chris Ogbonnaya and Keith Toston were vying for the backup job.
