Mitchell (lower body) was a full participant in Wednesday's joint practice with the Patriots, Tim McManus of ESPN.com reports.
Mitchell lined up against former teammate A.J. Brown multiple times throughout the session, making for a spectacular battle. The cornerback has been dealing with a lower-body issue since last Wednesday and is finally ready to return to the field. The All-Pro's return is a huge boost to the Eagles' starting secondary as they get ready to take on the Patriots in Saturday's preseason showdown.
