The Miami Dolphins signed defensive end Robert Nkemdiche on Thursday and added him to the active/physically unable to perform list.
The Arizona Cardinals, who drafted Nkemdiche in the first round of the 2016 draft, had waived him on July 27, a day after he arrived at training camp out of shape.
Nkemdiche has been recovering from ACL surgery in December.
Nkemdiche was a college teammate of Dolphins left tackle Laremy Tunsil at Ole Miss. The Dolphins checked in with Tunsil about Nkemdiche's character before making the move and were satisfied with what he told them.
