Williams (knee) was a limited participant at Wednesday's practice, Darren Urban of the Cardinals' official site reports.
Along with Williams, No. 1 running back James Conner (ribs) also returned to practice as a limited participant, indicating the position group is getting close to being back to full strength. An active Conner on Sunday in Minnesota likely would be Arizona's lead runner, but he could yield reps to Williams (if active) and Eno Benjamin. In five appearances this season, Williams averaged 5.9 yards per carry on his 16 rushes while scoring one touchdown.
