Ertz (hamstring) doesn't have a designation for Saturday's contest versus the Colts, Darren Urban of the Cardinals' official site reports.
Ertz kicked off Week 16 prep with back-to-back limited listings on Cardinals injury reports, only to cap it with a full showing at Thursday's practice. He's thus set to take on an Indianapolis defense that has allowed the most total yards (949) and fifth-most touchdowns (eight, tied with three other teams) to tight ends this season.
