Conner practiced in a limited capacity Wednesday due to a back injury, Darren Urban of the Cardinals' official site reports.
The oft-injured running back is dealing with his second health concern of the season after enduring some practice limitations during Week 2 prep due to a calf issue. His status will be one to watch closely as the week goes on, but so long as Conner is a full practice participant by Friday, he'll have a good chance at approaching Sunday's game in San Francisco without an injury designation. Through three games, Conner has easily paced the Cardinals backfield to the tune of 58 touches for 292 yards from scrimmage and two touchdowns.
