Foster (groin) has been ruled out for Sunday's game against Cleveland, Armando Salguero of the Miami Herald reports.
Absent from practice all week, Foster was never a good bet to play in Sunday's favorable matchup. Jay Ajayi and Kenyan Drake will likely split most of the backfield work, though Damien Williams and/or Isaiah Pead could potentially also be involved. Miami has yet to name a replacement starter.
Howard has been named a starter at corner, Armando Salguero of the Miami Herald reports.
Howard was expected to start for Miami and the announcement from coach Adam Gase is simply confirmation. Look for Bobby McCain and Tony Lippett to see time in nickel and dime packages with Howard as the starter.
Jenkins (knee) is questionable for Sunday's contest against the Browns.
Although Jenkins missed Wednesday's practice, he managed to participate on both Thursday and Friday, although he was limited in both sessions. If he's unable to play, Neville Hewitt projects to get the start at linebacker.
Jones has signed a one-year contract with the Dolphins, NFL.com's Ian Rapoport reports.
Jones' deal is reportedly worth more than $1.5 million, and although he's recovering from offseason knee surgery, the veteran will help Miami's options while Cameron Wake comes back from his Achilles tear. A starter in 31 of 32 games for the Lions the past two years, Jones posted 31 tackles and 4.5 sacks last season.
Misi restructured his contract with the Dolphins on Saturday.
The Dolphins restructured their deals with Misi and Ndamukong Suh, and released Greg Jennings, freeing up some cap room to work with this offseason. Misi tallied a career-high 78 tackles (59 solo) in 13 games last season but failed to record a sack.
Parker (hamstring) is listed as questionable for Sunday's game against the Browns, the Miami Herald reports.
Parker was limited throughout practice this week due to a hamstring ailment that he hasn't completely ridded himself of yet. Still, after making his season debut to the tune of eight catches (on 13 targets) for 106 yards, it seems likely that Parker will suit up again Sunday. While he status will need to be confirmed, his matchup against the Browns appears to favor another strong showing from the second-year standout.
After suffering a knee injury in Saturday's preseason game, Dolphins center Mike Pouncey didn't express much concern, a feeling that would prove to be valid, as an MRI came back negative and the lineman was back at practice Monday, per the Miami Herald.
Vigil (back) was placed on the Dolphins' reserve/NFI list on Tuesday.
Vigil has been dealing with a nagging back injury as of late, and will now be sidelined for the first six weeks of the regular season. When healthy, he'll likely return to a special teams role in which he recorded 18 tackles and a blocked punt across 16 games during the 2015 campaign.
Jordan (knee) will be placed on the reserve/non-football injury list to start the season, ruling him out for the first six weeks, NFL.com's Ian Rapoport reports.
Picked No. 3 overall in 2013, the 26-year-old Jordan was suspended for all of 2015 due to a repeat violation of the NFL's substance abuse policy. Although he was conditionally reinstated by the league, Jordan hasn't been able to practice while recovering from offseason knee surgery. He has just three sacks in 16 career appearances.
