Pickens (hamstring) was a limited participant in Wednesday's practice, Tommy Yarrish of the Cowboys' official site reports.
Pickens maintained his activity level from last week, when he entered the weekend listed as questionable before the Cowboys included him among their inactives for this past Sunday's game at Indianapolis. Thus, he may need to get back to full Thursday and/or Friday to avoid a designation ahead of Sunday's contest against the 49ers.
