Bills DT Kyle Williams (groin) is questionable for Sunday's game against the Colts. According to the AP, coaches expect Williams to play. He carries IDP upside against a struggling O-line that will be without C Ryan Kelly.

Bills DE Kyle Williams (back) and LBs Preston Brown (foot) and Zach Brown (illness) are active for today's game against the Jets. All 3 entered the day questionable but are good to go in your IDP lineups.

Bills LB Preston Brown (foot) and DE Kyle Williams (back) are both active for today's game against the Dolphins. Each is OK to use at his normal level in IDP lineups. Williams carries significant upside for DL slots. The Bills team D also carries upside at home against Matt Moore and a stuttering Miami run game.

Bills LB Preston Brown (foot) and DE Kyle Williams (back) are questionable for Sunday's game against the Dolphins. Both put in limited practices Thursday and Friday. Williams played through a questionable tag last week. We'll check on their statuses Saturday.

Bills DT Kyle Williams (back) and LB Zach Brown (ankle) are active for today's game against the Browns. Both should be fine to toss into IDP lineups in an upside matchup.

Bills DT Kyle Williams (back) returned to limited practice Friday after missing the 1st 2 days and last Sunday's game against the Steelers. Williams will be a game-time decision for this Sunday's game against the Browns, according to The Associated Press. We'll see about his status Sunday, though there's obvious risk even if he's active.

Bills DT Kyle Williams (back) is inactive for today's game against the Steelers. His back "locked up" Thursday night and kept him out of Friday's practice. Williams' absence weakens both the run defense and pass rush for a D dealing with a tough Steelers squad.

Bills DT Kyle Williams missed practice Friday and is questionable for Sunday's game against the Steelers after his back "locked up" Thursday night, according to ESPN's Mike Rodak. HC Rex Ryan admitted he's "concerned" about Williams' status for the game. Even if he does play, the back situation would seem to add some risk. Try to make other plans on the D-line in your IDP league, if you can.

As expected, Bills DL Marcell Dareus (hamstring) is inactive for the 3rd straight game today with a hamstring injury. Buffalo will have DL Kyle Williams (neck), however, after he entered the weekend questionable.

Bills DL Marcell Dareus is doubtful once again for Week 7 with the hamstring injury that has dogged him since his return from the 4-game suspension. He sat out practice all week and thus doesn't look particularly close to returning to full strength. Bills DL Kyle Williams is questionable, as well, after showing up on Thursday's injury report with a neck issue. He put in limited workouts Thursday and Friday. The defense did, however, get a potential boost this week by activating rookie OLB Shaq Lawson (shoulder) after he opened the season on the PUP list. We'll see what kind of role Lawson's ready to play in his 1st NFL action.

Bills DT Kyle Williams left Sunday's game after suffering a sprained PCL, according to Sal Capaccio of WGR 550. The team will reportedly test it further, though, to check on the extent of the damage. If it does prove to be a sprained ligament, we should expect Williams to miss about 3 weeks. If we don't get a more positive diagnosis, then IDP owners can go ahead and drop Williams.

Bills S Aaron Williams (wrist) is inactive for Sunday's matchup with the Patriots. It's a somewhat surprising move after he put in limited practices all week.  Buffalo will however, have 3 other "questionable" defenders in the lineup.  DT Kyle Williams (knee), LB Nigel Bradham (knee) and LB Brandon Spikes (ribs) are all active.  Williams stands as a high-upside IDP option worth playing in most lineups.  Bradham's risky but has produced well when healthy this year.  Spikes' playing time has fluctuated too much to make him a reliable fantasy option, though he does present some revenge-game potential against his old team.

The Bills list defensive starters LB Nigel Bradham, LB Brandon Spikes, DT Kyle Williams and S Aaron Williams as questionable for Sunday's battle with the Patriots.  WGR 550 reports that Bradham is "likely to be a true game-time decision," with Williams even less likely to play.  IDP owners should plan to be without both a week after each sat out the Lions win with a knee injury.  If Bradham doesn't play, it'll help the fantasy outlook for rookie LB Preston Brown.  We've seen no indication that MLB Spikes won't play, but his inconsistent playing time makes him a very iffy IDP prospect.  Williams put in limited practices all week despite a wrist injury.  We'd bet on him playing against the Pats.

The Bills have listed DT Kyle Williams and OLB Nigel Bradham as doubtful for Sunday's clash with the Lions.  Both defenders are dealing with knee injuries suffered in Week 4 and missed practice all week.  Rookie Preston Brown will start in Bradham's place and continue to carry intriguing IDP upside.  He's worth starting in most fantasy leagues with defensive players.  We moved him way up the Week 5 IDP rankings.

The Bills might need to go without 2 key defensive starters Sunday at Detroit.  DT Kyle Williams and OLB Nigel Bradham have missed practice Wednesday and Thursday because of the knee injuries they suffered in Week 4.  Williams' absence would hurt the overall D more, as he's 1 of the best interior linemen in the league.  Bradham has performed well in his 1st shot as a full-time player.  But if he's out Sunday, rookie Preston Brown looks like a capable replacement.  Make sure you get some insurance if you're hoping to have Williams or Bradham in your IDP lineup.

Bills LB Nigel Bradham and DT Kyle Williams left Sunday's loss at Houston with knee injuries.  The Buffalo News reports that a "team source" believes neither injury is too serious, but both starters are due for Monday MRIs.  We'll keep an eye out for official diagnoses, especially considering that each player has been an IDP factor.  If Bradham misses any further time, it would clear room for impressive rookie Preston Brown to remain on the field.  If Bradham's OK, though, it could render Brown a part-timer.  He wasn't in the starting lineup in Week 4.

Bills DT Kyle Williams is active today against the Falcons.  He turned up questionable after awaking with lower-back spasms Friday.  He's a strong IDP option in a high-ceiling matchup.

Bills DT Kyle Williams is questionable for Sunday's game against the Falcons after he awoke with lower-back spasms Friday morning.  The team website reports that Williams has never experienced back spasms before but that he's cautiously optimistic for the game.  We'd give an active Williams benefit of the doubt.  He's a top talent in a favorable matchup.

The Buffalo News reports that Bills DT Kyle Williams is expected to miss the rest of the season. He missed the past 3 games with a foot injury that is now being described as bone spurs rubbing against his Achilles tendon. Rookie Marcell Dareus has taken over primary NT reps when the team lines up in a 3-4 front. Spencer Johnson and Alex Carrington have seen significant snap increases as well in Williams' absence, as the Bills have put forth plenty of 4-3 looks.

There is now concern in Buffalo that DT Kyle Williams might be done for the season with the foot injury that cost him Week 6. NFL Network's Jason La Canfora reported this week that the team plans to wait a bit longer before placing Williams on IR, just to see if rest can bring him back this season. IDP owners have probably already dumped the player, though, who wasn't putting up numbers anyway. Williams' continued absence is bad news for the Buffalo run D, too. Still not stellar, the Bills had improved some against the run this year. The matchup is undeniably positive for RBs as long as Williams is sidelined.
