What happened: The agreement is a practice squad deal. Ertz played in Philadelphia from 2013-21. He earned three Pro Bowl selections and helped win the franchise's first Super Bowl title.

Why it matters: Philadelphia adds a veteran with nine seasons in its system. That familiarity shortens the ramp for depth duties down the stretch.

What to watch: Watch for a potential elevation to the active roster. His role will hinge on weekly tight-end availability.
