In the last two weeks, the Dolphins lost their Pro Bowl safety and a former Pro Bowl running back.
On Tuesday, they replaced one with the roster spot created by the retirement of the other.
The Dolphins signed former Bills, Redskins safety Bacarri Rambo. He will presumably fill the roster spot vacated by Arian Foster, who announced his retirement late Monday. The Dolphins placed Foster on the reserve-retired list Tuesday, creating the roster opening.
Miami has a need at safety after losing Reshad Jones for the year with a rotator cuff injury. Rambo, like Jones, played his collegiate ball at the University of Georgia.
A sixth-round pick in the 2013 draft, Rambo spent his first year and a half with the Redskins before joining the Bills in late 2014. The 6-foot, 211-pound safety started eight games for Buffalo last year, recording 62 tackles and a sack. He has three career interceptions.
The Dolphins were shopping for safeties Tuesday, and decided on Rambo. They also brought in James Ihedigbo, Major Wright, and Sergio Brown for workouts, ESPN first reported.
