The Ravens have some questions with their backup cornerbacks because Rashaan Melvin has been sidelined with a thigh injury and rookie fourth-round pick Tray Walker is inexperienced and raw. When starter Lardarius Webb was briefly hurst in Sunday's loss at Oakland, Kyle Arrington moved to Webb's spot and safety Terrence Brooks lined up at nickelback.
This also comes a day after the Ravens' secondary allowed Raiders quarterback Derek Carr to throw for 351 yards and three touchdowns in a 37-33 loss.
Davis, a third-round pick in 2013, hasn't played a snap in the Dolphins' first two games. He is nearly 10 months removed from anterior cruciate ligament surgery on his right knee.
In 15 career games, Davis has 25 tackles, no interceptions and three passes defensed.
