Jackson was pulled in the second quarter of Sunday's victory over the Washington Redskins because of a groin strain. Initially, it appeared that the Rams running back was being pulled after spiking the ball and drawing an unsportsmanlike conduct penalty, but that was not the case.
RB @sj39had a strained groin. That's why he did not return to game. He said in locker room that it's not too bad and should heal quickly.— St. Louis Rams (@STLouisRams) September 17, 2012
Saffold made a surprising return to the team after a neck injury in Week 1 made him doubtful for this weekend's game. He didn't last long, injuring his left knee after recovering a Sam Bradford fumble. His status remains unclear at this point.
