Pickens (shoulder/hamstring) was limited at Wednesday's practice, Jon Machota of The Athletic reports.
Pickens endured some practice restrictions last week due to a shoulder issue, but a hamstring injury is combining with the existing health concern to impact his on-field work to kick off Week 8 prep. He'll have two more opportunities to get back to full this week, at which point the Cowboys may tag him with a designation ahead of Sunday's game against the Cardinals.
