Abdullah (shoulder) increased his activity on both Saturday and Sunday, MLive.com reports.
During the opening of training camp Friday, Abdullah was seen in a red no-contact jersey, likely due to his offseason surgery to repair a torn labrum. Head coach Jim Caldwell sidestepped the state of Abdullah's health in a media session, but the running back has subsequently taken the field as the Lions' No. 1 running back and as a punt returner. It's unclear if Abdullah has been cleared for a full session through three days, though.
