Cooper (knee/ankle) was a limited participant in Wednesday's practice, David Helman of the Cowboys' official site reports.
Per Todd Archer of ESPN.com, Cooper jammed his knee during Monday's win over the Giants, but he stayed in the game and finished the night with four catches for a team-high 80 yards and one touchdown. It's encouraging that the No. 1 receiver wasn't held out of Wednesday's jog-through practice entirely, and there's not yet any reason to suspect that Cooper is in danger of missing time. He'll have two more chances to upgrade to a full participant ahead of Sunday's tilt with the Vikings.
