Williams won't return to Friday's game against the Browns due to a knee injury.

EDGE Analysis

Williams injured his knee in the first half of Friday's game and was taken to the locker room. The team hasn't clarified the specifics or the severity of the issue to this point. Look for Adolphus Washington and Harrison Phillips to see some extra reps as long as Williams is out.

Williams has signed a one-year deal to remain with the Bills, Chris Brown of the team's official site reports.

EDGE Analysis

Williams, who turns 35 in June, logged 41 tackles and three sacks in 16 games for the Bills in 2017. While he's not quite the IDP force he was earlier in his career, the five-time Pro Bowler remains a key cog in the Buffalo defense, while bringing valuable leadership ability to the table.

Williams is planning on returning for at least one more season, Mike Rodak of ESPN.com reports.

EDGE Analysis

Williams has been mulling retirement since the Bills were bounced from the playoffs and it appears he still isn't 100 percent certain about a decision. Though he's leaning towards a return, that decision has yet to be set in stone.

Williams, who played 45 defensive snaps and logged a tackle in his first-ever playoff game Sunday in a 12-season NFL career, is undecided about his future, Chris Brown of the Bills' official site reports. "I don't have one," the veteran said about his timetable for a decision. "We'll meet with the people who need to be met with, and discuss it and we'll see where we go."

EDGE Analysis

Williams was the heart and soul of the Bills' surprising run to the playoffs and can still play at a high level, but there's a lot of wear and tear on his body after all this time in the league, plus there's something to be said for finally reaching the playoffs and helping the team snap a 17-season drought. It seems unlikely he'd start fresh with a new team, so we'll see if he wants to come back for one more go-round with Sean McDermott's process.

Williams (groin) is active for Sunday's contest against the Patriots.

EDGE Analysis

Williams only registered one limited practice this week but there wasn't much doubt about the veteran lineman's ability to play come Sunday. He's expected to see his normal role along the starting defensive line.

Williams (groin) will be limited at practice Friday and listed as questionable for Sunday's game against the Patriots, Chris Brown of the Bills' official site reports.

EDGE Analysis

Williams is enough of a veteran that he could probably go the entire week without practicing and still play capably Sunday. With his career winding down and without a single playoff game on his fine resume, there's no way Williams is missing Week 16.

Williams (groin) missed practice for the second straight day Thursday, Chris Brown of the Bills' official site reports.

EDGE Analysis

Williams has been muddling through this for several weeks, but given this could be the final season for the long-time veteran there's almost no way he's going to miss the last two weeks as the Bills try to fight for a playoff spot, something Williams has never been a part of in his otherwise successful career.

Williams (groin) wasn't given an injury tag Friday and is in line to play Sunday against Miami.

EDGE Analysis

Williams will avoid missing his first game of the season, which is valuable in a game with serious playoff implications. The veteran defensive tackle averages just 2.5 tackles per game, though, so without the help of sacks, his fantasy value is underwhelming.

Williams, who sat out Wednesday's practice with a groin injury, practiced on a limited basis Thursday, Chris Brown of the Bills' official site reports.

EDGE Analysis

The 34-year-old is frequently rested during the practice week, so even though he does have a groin injury it appears to be minor in nature. Williams will be out there Sunday as the Bills enter a very important game against the Dolphins.

Williams won't practice Wednesday due to a groin injury, WGR Sports Radio 550 Buffalo reports.

EDGE Analysis

It's believed that Williams picked up the injury during the Bills' 13-7 overtime victory over the Colts on Sunday. The significance of the setback isn't yet clear, but if Williams puts in a full practice before the end of the week, he could avoid an injury designation for the Week 15 matchup with the Dolphins.
