Dunbar signed a deal to join the Cardinals' practice squad Tuesday, Ian Rapoport of NFL Network reports.
Dunbar signed with the Lions this offseason but was released during training camp. Prior to signing with Arizona, Dunbar also worked out with the Bills. While it may take some time for him to get acclimated to his new team, Dunbar should be expected to join the active roster at some point in the coming weeks. He could provide solid play in the secondary, as he picked off four passes in 2019 across only 11 games.
