Cooper (ankle) is in pads during Monday's Cowboys Night practice, Todd Archer of ESPN.com reports.
Cooper opened training camp on the PUP list, the result of residual irritation from January ankle surgery. The Cowboys activated him last Tuesday, but Monday's session marked the first time he donned pads this summer. Per Jon Machota of The Athletic, Cooper proceeded to take part in individual drills, but it's very likely that he's easing into action to avoid any sort of setback.
