Williams will retire from football following the team's finale Sunday against the Dolphins, Chris Brown of the Bills' official site reports.

EDGE Analysis

The Bills will say goodbye to one of the best defensive players in team history, a fifth-rounder that ended up out kicking his draft slotting in almost every imaginable way. Williams will finish his career with 48.5 sacks (plus whatever he might get Sunday) and over 600 tackles. His relentless play, a style which never really tapered off even in his mid-30's, and leadership in the locker room will be missed by a team that's been playing for the future for several weeks.

Williams (back) practiced fully Friday and is not listed on the injury report for Sunday's game at New England.

EDGE Analysis

With his career starting to wind down, even if Williams was on the injury report it'd take a lot to keep him off the field with perhaps his last crack at the Patriots. Williams and Lorenzo Alexander remain the heart and soul of the defense even into their mid-30's, and it'll be interesting to see if the Bills take one more stab at recruiting them back for another season.

Williams (back) was a limited participant in Thursday's practice.

EDGE Analysis

Williams hasn't missed any game time due to his back injury was held out of practice entirely Wednesday. His limited session bodes well for his Week 16 status, though he should still be considered questionable for the time being.

Williams (back) did not practice Wednesday, Chris Brown of the Bills' official site reports.

EDGE Analysis

It's unclear where Williams picked up the back injury, but his absence from Wednesday's practice sheds some doubt on his availability for Sunday's tilt against the Patriots. The veteran defensive lineman has not yet missed a game this season, but if Williams were unable to go Week 16 expect Jordan Phillips to benefit from an uptick in snaps.

Williams recorded seven tackles (four solo), including 1.5 sacks, in Sunday's win over Jacksonville.

EDGE Analysis

Williams turned back the clock a bit Sunday. His seven tackles were his most in a game since 2016 and his 1.5 sacks gives him five on the season. The veteran defensive lineman is having another quality year, though his 24 tackles through 11 games are low by his standards. He'll look to continue his strong play as the Bills aim for a third straight win when they take on they Dolphins in Week 13.

Williams posted three tackles, 2.0 sacks and a forced fumble during Sunday's loss to the Texans.

EDGE Analysis

Williams may be 35 like his teammate Lorenzo Alexander, but the two of them are playing like guys a decade younger. While Williams doesn't see a full allotment of plays any more and probably doesn't put up the stats to make him IDP worthy -- 12 tackles, 3.5 sacks, one forced fumble -- he's still a starter putting up meaningful production for one of the league's better (and more surprising) defenses. The Buffalo defense is simply better when its heart and soul is on the field.

Williams, who injured his knee in the second preseason game and didn't return to practice until Monday, practiced fully all week and does not appear on the Week 1 injury report,, Chris Brown of the Bills' official site reports.

EDGE Analysis

Coach Sean McDermott has declared his veteran leader ready to go for Sunday's opener in Baltimore, where he'll work with Star Lotulelei and rookie Harrison Phillips to form a pretty solid interior defensive line.

Williams returned to practice Monday for the first time since injuring his knee in the second preseason game, Jay Skurski of The Buffalo News reports.

EDGE Analysis

Williams and the Bills won't know until later in the week if he'll be able to go for the opener in Baltimore. Even if he plays, the team is prepared to give rookie Harrison Phillips a decent amount of playing time behind his mentor, based on Phillips' strong preseason as well as trying to manage Williams' health.

Williams (knee) is "week-to-week" after tests for a torn ACL came back negative, Mike Rodak of ESPN.com reports.

EDGE Analysis

Williams will likely miss the rest of the preseason and his absence could leak into the regular season as well. The 13-year pro recorded 105 tackles and eight sacks over the last two seasons, and Adolphus Washington will see an uptick in snaps while Williams sits out.

Initial tests suggest Williams (knee) avoided an ACL tear and could return at some point in 2018, Ian Rapoport of NFL Network reports.

EDGE Analysis

The veteran defensive tackle has only missed significant time in two of his 12 seasons prior to 2018, but it appears Williams is set to be sidelined for an extended run this season after suffering the injury during Friday's preseason contest. More information on his injury should surface when the MRI results are in.
