Mike Garafolo of NFL Media reports that the Dolphins are signing S Bacarri Rambo to a contract on Tuesday.
Miami just lost Pro Bowl S Reshad Jones for the season last week, so they are clearly in need of some help at the position.
Rambo, 26, is a former sixth-round pick of the Redskins back in 2013. He lasted just over a year in Washington before he was waived at the start of the 2014 season.
Rambo later caught on with the Bills towards the end of the 2014 season before testing the open market as a free agent this year.
In 2015, Rambo appeared in 15 games for the Bills and recorded 62 tackles, one sack, an interception, two forced fumbles, a recovery and six pass defenses. Pro Football Focus had him rated as the No. 57 safety out of 89 qualifying players.
