The Dolphins placed DuBose on injured reserve Saturday due to a shoulder injury.
DuBose popped up on the Dolphins' injury report Wednesday with a shoulder injury, and he was unable to practice Thursday and Friday. The severity of the injury isn't clear, but his move to IR will force him to sit out for at least the next four games. The earliest DuBose will be able to return will be Week 8 against the Cardinals on Oct. 27. Both Dee Eskridge and Erik Ezukanma were elevated from the practice squad to the active roster ahead of Sunday's game against the Seahawks, and one of them could be signed to the active roster for as long as DuBose is sidelined.
