The Birds waived Miller last summer, leading him to the Panthers. He was later released, freeing him up to return to the Eagles as a practice squad player. The Cardinals inked him to a futures deal in January, but he became a free agent last week when he was dropped to make room for defensive tackle Xavier Williams.
Now, Miller will compete for a spot behind projected starters Dante Fowler and Jacob Tuioti-Mariner. Jonathan Bullard, Barkevious Mingo, and fifth-round pick Ta’Quon Graham are also in the mix at defensive end.
