Jones (knee) is inactive Sunday against the Jaguars.
With Latavius Murray (toe) back in action, DeAndre Washington and Jalen Richard will round out the Raiders' running back corps. Jones wouldn't have been much of a threat to siphon backup carries from the latter two anyway, had he been available to play.
Smith (suspension) has entered a treatment center, ESPN reports.
Smith's reason for seeking treatment is unclear, but it comes just days after a Periscope video titled "Fire up session" surfaced of an unidentified man, suspected to be him, talking about a hand-rolled cigarette shown on screen. In wake of that video, which appeared under an account previously used by Smith, the NFL has launched an investigation into whether he violated protocols required of a suspended player seeking reinstatement from a substance abuse violation. While that investigation continues, Smith's move to now enter a treatment facility hardly seems coincidental, and more details regarding his situation should surface soon.
Cameron (concussion) is inactive for Sunday's Week 7 tilt versus the Bills, the team's official site reports.
Cameron will remain sidelined with the concussion that's prevented him from playing since Week 4. With position mate Dion Sims also out, MarQueis Gray and Dominique Jones will continue to man the position for the Dolphins.
Sims (concussion) is inactive for Sunday's Week 7 tilt versus the Bills, the team's official site reports.
Sims suffered the concussion in last Sunday's victory over the Steelers and did not practice at all this past week. His absence, combined with that of Jordan Cameron's (concussion), leaves MarQueis Gray and Dominique Jones as the Dolphins' tight ends for the Week 7 contest.
Vigil (back) returned to practice Wednesday, the Miami Herald reports.
Although eligible to practice, Vigil remains on the Dolphins' NFI list for the time being. He only participated in individual drills Wednesday, so he likely isn't completely recovered from the back ailment and remains without a definite timeline to return to game action.
