Hill (ankle/personal) doesn't have an injury designation for Sunday's game against the Bills, Travis Wingfield of the Dolphins' official site reports.
Hill was a limited participant in Wednesday's practice and didn't practice Thursday, but the lack of practice participation was likely due more to the fallout from learning about a fire that occurred at his residence than the ankle injury that he played through in the previous two games. He returned to full participation Friday, clearing up any lingering concern about his availability heading into Sunday. Even though the Dolphins have already clinched a playoff spot, they'll have plenty of motivation Sunday against the Bills, as the AFC East crown along with the No. 2 seed in the playoffs will be up for grabs between the two teams. With that in mind, Hill is likely to handle his usual heavy workload in the regular-season finale.
