St. Louis Rams running back Steven Jackson has not played since early in the second quarter when he drew an unsportsmanlike conduct penalty for spiking the ball after he was ruled short of the goal line on a third-down carry from the 1.
The Rams went with rookies Isaiah Pead and Daryl Richardson in the home opener against Washington on Sunday while Jackson stood on the sideline, helmet in hand. A team spokesman said Jackson was fine physically.
One play before the penalty, referees ruled that Jackson had lost a fumble at the 1. The call was reversed when the Rams challenged.
Jackson had 58 yards on nine carries. He's the Rams' career rushing leader and entered the year with seven consecutive 1,000-yard seasons.
