The signing did not happen before the NFL released its transaction report, so we do not know what other roster moves the Cardinals are making to accommodate him.
Dunbar has been in the league since 2015 when he entered the league as an undrafted rookie out of Florida.
He has 10 career interceptions, with a career-high four in 2019.
He has played in 64 career games, starting 31.
He is talented but also has had issues with durability. In six NFL seasons, he has been on injured reserve twice and never has played a full 16-game season.
Rapoport’s tweet suggests that Dunbar is signing to join the team on the active roster. That might not be the case.
According to Arizona Sports 98.7 FM’s John Gambadoro, it is likely a signing to the practice squad.
A practice squad signing would mean he would have time to learn the defense but already be with the team should the need to promote him arise.
