The Cardinals brought back safety Harlan Miller Wednesday on a one-year deal, giving the team another potential defensive back in the mix.

Miller, the team's sixth-round pick in 2016, was released in early May as the Cardinals made room to sign their draft class. The move was needed after the Cardinals had to waive/injured cornerback Lou Young III, who suffered a hamstring injury in a recent practice.

Miller has played in a total of seven games over two seasons while splitting time on both the active roster and practice squad. He had an interception in the 2016 season finale. The Cardinals had signed three undrafted rookies at safety following the draft, and two remain in the fight for roster spots -- A.J. Howard and Zeke Turner.

The Cardinals also finished up the University of Phoenix Stadium portion of training camp Wednesday. They play in New Orleans Friday, and resume practice at the team's Tempe facility next week.
