Dolphins MLB Kiko Alonso (hamstring) is active for today's game against the Bills, playing through a "questionable" tag for the 2nd straight week. He's OK to use at his normal level though not a special IDP option. DE Mario Williams (ankle) is also active but shouldn't be in IDP lineups.

As expected, Dolhins MLB Kiko Alonso (thumb, hamstring), OLB Jelani Jenkins (knee) and DE Mario Williams (ankle) are out for today’s game against the Cardinals. All 3 entered the day doubtful. According to the Sun-Sentinel, Alonso's hamstring has hampered him more than his repaired thumb fracture this week. Second-year LB Mike Hull is expected to start in Alonso's place, with Spencer Paysinger likely in for Jenkins. (Paysinger was questionable with an ankle injury but is active.) Avoid the Miami LB situation in your IDP lineups. S Isa Abdul-Quddus (neck) is active an ready for normal fantasy usage. CB Xavien Howard (knee) remains out despite advancing to a questionable tag this week.

Dolphins DT Ndamukong Suh (knee), LB Jelani Jenkins (knee) and DE Mario Williams (ankle) are all active for today's game against the 49ers. All 3 entered the day questionable. Suh should be the only one in play for IDP leagues. Use him as you normally would.

Dolphins DE Mario Williams is active for Sunday's game against the Patriots. He has apparently progressed beyond the concussion that knocked him out of the opener in Seattle. He's OK to use in IDP leagues as you normally would.

Dolphins DE Mario Williams suffered a concussion in Sunday's loss at Seattle and will need to pass through the league protocol before returning. We'll keep an eye on his status this week leading up to a Sunday trip to New England. Williams contributed 2 total tackles (1 solo, 1 assist) and a sack in his Miami debut.

NFL Network's Ian Rapoport reports that former Bills DE Mario Williams has agreed to a 2-year deal with the Dolphins. The 31-year-old is coming off a 5-sack season, the worst total since his rookie year for any campaign in which Williams played more than 5 games. (And Williams played through a plantar fascia injury in that rookie season.) He spoke out about not fitting well in HC Rex Ryan's scheme in 2015, however, and Williams' career-high 14.5 sacks in 2014 makes it easier to believe he can still produce. Miami might start Williams at left DE after Cameron Wake suffered a torn Achilles' tendon in late October. Left DE Olivier Vernon also heads into free agency with just the transition tag, and thus could move on.

As expected, the Bills on Tuesday released DE Mario Williams. The veteran was set to count $19.9 million against the 2016 cap in the penultimate year of a $100 million contract. That's especially rich money when you're coming off a 5-sack season. Williams voiced concerns with how he fit in HC Rex Ryan's scheme during last season and seems unlikely to return to Buffalo on a new deal. He could still deliver pass-rushing value in a different system, though, and figures to find interest on the open market. We'll see how the Bills choose to replace Williams and whether the Ryan brothers will adjust the defense to better leverage 1 of the league's best D-line groups.

Bills DE Mario Williams (illness) is active today against Washington. He's having a rough year, though, and faces a tough sack matchup. He's not a good IDP option for Week 15.

Bills DE Mario Williams is officially questionable for Sunday's game at Washington because of an illness. But multiple reports say he's expected to play. He has proved terrible for IDP owners this year, so you should be trying to find a different option anyway.

Bills DE Mario Williams (foot) is active, as expected, for today's game against the Texans. He's had a rough year to date, including just 3 sacks, but is OK to use if you normally would in your IDP league.

Bills DE Mario Williams is probable for Sunday's game against the Texans after putting in a full practice Friday. He missed last week's loss at Kansas City with a foot  injury. “I think Mario looks good,” Ryan said, via the Buffalo News. “He might not be 100 percent, but he’s good enough for us.” Williams has just 3 sacks on the season, making him a shaky IDP option. But having him in the lineup is certainly better for the Bills' D.

The Bills expect DE Mario Williams (foot) to miss Sunday's game at Kansas City, according to The Associated Press, after he missed his 2nd straight day of practice Thursday. Williams' absence certainly won't help the team defense, but it doesn't significantly alter the outlook for fantasy.

Update: The Bills have ruled Williams out.

the Bills on Thursday placed OLB/DE Mario Williams on the active/non-football injury list with an undisclosed ailment. ESPN's Mike Rodak reports that the team calls it a "minor" issue. As long as that proves true, we won't worry about Buffalo's top sacker.

HC Doug Marrone told reporters Thursday that DE Mario Williams had hip surgery this offseason.  That'll keep the veteran out of OTAs, but Marrone expects him to be ready for the start of training camp.  Williams has overcome much more significant injury issues than this, including plantar fasciitis last summer and a wrist fracture that required surgery the season before.  We won't change our 2014 IDP rankings for this unless Williams gives us reason to come July.

ESPN's Adam Schefter reports that Bills DE Mario Williams suffered an ankle sprain in the Week 3 loss to the Jets.  Williams reportedly expects to play in Week 4 against the Ravens, as long as his ankle improves throughout the week.  We recommend lining up a potential replacement for Williams' DL slot in your IDP lineup.  HC Doug Marrone also said that DL Marcell Dareus will be "fine" following his own ankle sprain.  We'll see when the injury reports start arriving later this week.  The Bills did, however, place DE Alex Carrington on IR with a torn left quad.

Bills DE Mario Williams was "limping mightily" after Sunday's loss to the Jets and headed for an X-ray, according to Tim Graham of the Buffalo News.  ESPN.com later reported that the team confirmed Williams was getting treatment but refused to specify the area of the injury.  We'll likely find out more specifics before long, but you should expect this kind of stuff from the Bills for at least the near future.  When HC Doug Marrone was at Syracuse, he commonly reported player injuries as merely "upper body" or "lower body."  Losing Williams for any amount of time would obviously hurt the Buffalo D and IDP owners.  We'll see what the team lets slip over the next couple of days.  Williams dealt with plantar fasciitis over the summer, an issue he also encountered in the past.  We'll see if this latest ailment is related.

Bills DE Mario Williams returned to camp on Wednesday and dressed for practice but didn't participate.  According to ESPN, Williams said the foot injury he left to have checked is "not that serious."  On riding the stationary bike instead of practicing, Williams said: "This is precaution. I'm just following orders."  You shouldn't worry about Williams' status heading into your IDP fantasy football draft.  But we'll certainly keep an eye on the situation.

Bills DE Mario Williams left training camp today to get his sore foot checked out by team doctors.  HC Doug Marrone said he had no news as of Monday evening.  Williams has played all 16 games in 5 of his 7 seasons, but he has been dinged up quite a bit.  That included playing most of last season's 1st half with a wrist that needed surgery and playing through plantar fasciitis in his rookie season.  A bothersome foot could obviously hurt Williams' performance even if it doesn't keep him off the field.  We'll see what happens here.

Finally, the Bills are reportedly ready to sign DE Mario Williams on Thursday afternoon. The former Texan has been in Buffalo since free agency started and was rumored to be near signing the whole time. He gives the Bills a tremendous D-line, along with DTs Marcell Dareus and Kyle Williams. Chris Kelsay is the best current bet to play LDE. Williams should be a top-10 IDP lineman in his new digs. He'll play next to easily the best set of DTs in his career -- arguably the best in the league.

Update: Williams' deal is worth $100 million over 6 years.  He gets $50 million guaranteed.  It's the richest contract for a defensive player in NFL history.
