Ertz was listed as limited on Thursday's practice report due to a shoulder injury, Darren Urban of the Cardinals' official site reports.
Ertz now has made exactly six appearances apiece for the Eagles and Cardinals this season, and he has 31 targets in both locales. Still, he's produced more in Arizona, with a 23-279-3 receiving line versus 18-189-2 in Philly prior to his midseason trade. Ertz is tending to a shoulder injury Week 14, but he'll have a pair of sessions to bump up to full before the Cards potentially give him a designation for Monday night's game against the Rams.
