Martin (hamstring) has been ruled out for Sunday's game in San Francisco.
Martin was seemingly on track to practice for the first time since he injured his hamstring in Week 2, but he then suffered a setback at some point last week, leaving him without a clear timetable to return. With Charles Sims (knee) also out of the picture, Jacquizz Rodgers is set to handle a heavy three-down workload in Sunday's favorable matchup against the leaky San Francisco run defense. Peyton Barber and Antone Smith will provide depth.
McCoy is expected to play Sunday against the 49ers, but on a potentially limited basis, Alex Marvez of Sporting News reports.
McCoy will be active Week 7 barring any pregame setbacks, but coach Dirk Koetter intends on monitoring the snap count of his top defensive tackle. John Hughes and Akeem Spence figure to see additional reps in the middle.
McDonald (hamstring) will not play against the 49ers on Sunday.
McDonald was able to return to practice after sitting out on Wednesday, but will be held out due to the lingering nature of hamstring injuries. However, he appears to have an optimistic chance of returning next week. Akeem Spence will get the start on Sunday as his replacement.
Shorts (hamstring) is expected to start at wide receiver opposite Mike Evans during Sunday's game against the 49ers, Jenna Laine of ESPN.com reports.
Despite Shorts being listed as questionable heading into the weekend, coach Dirk Koetter plans to fill Vincent Jackson's (knee) vacancy in the starting lineup with Shorts. This would leave Adam Humphries and Russell Shepard as the No. 3 and No. 4 options at wide receiver, while tight end Cameron Brate also figures to play a role in the passing game.
James (undisclosed) reached an injury settlement with the Buccaneers on Wednesday, ESPN reports.
Following a three-year stint with the Bucs, the team decided to part ways with James due to a vague injury he can't seem to overcome. In the wake of his release, Tampa Bay promoted rookie Peyton Barber from the practice squad and plucked Jacquizz Rodgers off the free agent market.
Bell (concussion) reached an injury settlement with the Buccaneers on Thursday, Aaron Wilson of the Houston Chronicle reports.
Bell suffered a concussion in Week 4's preseason finale against the Redskins, leaving him on the sidelines for an extended amount of time. The team decided to part ways with wideout instead of holding him on IR for the year.
Despite being listed as a full practice participant all week, Foster (hamstring) is listed as questionable for Sunday's game against the Bills.
Foster's full practice participation at practice suggests that he's likely to be active for Sunday's 1:00 ET tilt, but the questionable designation is an acknowledgment that the veteran back -- who missed time earlier this season -- is not yet 100 percent. Meanwhile, Jay Ajayi's 25-carry, 204-yard rushing effort in Week 6 puts him atop the Dolphins' RB pecking order for now.
Paysinger (hamstring/calf) is questionable to play against the Bills on Sunday.
Paysinger sustained a leg injury in Thursday's practice, but it's unclear what he's specifically dealing with. If he's unable to play, Donald Butler will step in as the Dolphins' starting strongside linebacker.
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.
