In need of running back help because of an ankle injury to Jesse Chatman, the Dolphins activated halfback Ricky Williams from the league's exempt list.
The Dolphins had until December to make a decision on Williams, but Chatman is listed as questionable with an ankle injury and wasn't moving well toward the end of the week. To make room for Williams, the Dolphins released running back Samkon Gado.
Williams is returning to the NFL after 18 months. He served a drug suspension that was extended from May until two weeks ago on the recommendation of the league's drug counselor. This summer, Williams moved to Boston and spent time with drug counselors reviewing his life and past habits.
It is not known whether he will be on the active roster for tonight's game against the Steelers (ESPN, 8:30 ET), but it is likely. Williams had a great week of practice and players on the team remarked how well he did and how much of an asset he could be for this game.
