Grant sustained a high-ankle sprain during Saturday's 26-25 win over the Raiders and is expected to miss Week 17, Ian Rapoport of NFL Network reports.
The timing of Grant's injury is inopportune for the Dolphins. With DeVante Parker (hamstring) coming off back-to-back absences and Preston Williams (foot) still on IR, the team could be without its top three wideouts heading into a Week 17 road game against the Bills. Rapoport called Grant a candidate for IR and said that he'll miss the regular-season finale, but the Dolphins themselves haven't yet officially ruled the 28-year-old out.
