Perine was signed Monday by the Dolphins off the Bengals' practice squad, Ian Rapoport of NFL Network reports.
Perine hasn't made much impact as a 2017 fourth-round pick, despite opportunities during stints with Washington and Cincinnati. Overall, he's averaged 3.5 YPC on 183 career rushes, hauled in 25 of 28 targets for 187 yards and scored two TDs in 27 career games. In his new home, Perine will provide depth to a Dolphins backfield that may be without Myles Gaskin (ankle) during Sunday's season finale in New England.
