"St. Louis Rams running back Steven Jackson, who injured a groin muscle Sunday vs. Washington, sat out of practice Thursday for a second consecutive day. Jackson's status for Sunday's game vs. Seattle remains uncertain and Rams coach Steve Spagnuolo has said Jackson is "day to day." If Jackson were unable to play, backup RB Kenneth Darby likely would get the bulk of the work Sunday." http://www.stltoday.com/sports/foot...cle_00bfe75c-ccc1-11df-8806-00127992bc8b.html
