St. Louis Rams running back Steven Jackson missed practice on Wednesday to continue to heal from a groin injury. Jackson was hurt in the Rams' 31-28 win over the Washington Redskins on Sunday.

Although Jackson's MRI earlier in the week yielded positive results, the Rams seem to be taking a cautious approach, as Jackson has dealt with groin problems in the past. He is listed as day-to-day on the team's injury report.

Jackson ran for 58 yards on nine carries, including a long of 20 yards, before being replaced by Daryl Richardson during the second quarter. Richardson had 15 carries for 83 yards in his stint at running back.

In addition to Jackson, fullback Brit Miller was also missing from practice as he deals with quad soreness.
