Hamilton (shoulder) has been downgraded to out for Sunday's contest against the Steelers.
Hamilton was a limited participant in practice all week with a shoulder injury suffered in Week 6, and apparently isn't recovering well enough to suit up against the Steelers. With Hamilton and defensive tackle Vince Valentine out Sunday, the Patriots will be short-handed along their defensive line.
Williams has missed several days of practice with an undisclosed injury.
Clearly behind Rob Gronkowski and Martellus Bennett on the Patriots' tight end depth chart, Williams is competing for depth slotting at the position along with Clay Harbor, A.J. Derby, Steven Scheu and Bear Pascoe.
Williams tore his left ACL during Wednesday's practice and he'll likely be placed on Injured Reserve, Jim McBride of the Boston Globe reports.
As expected, Williams' injury was a serious one as he was seen on crutches Thursday awaiting the unfortunate results. This ensures Clay Harbor's spot as the No. 3 option at tight end behind Rob Gronkowski and Martellus Bennett heading into the 2016 season, as Williams enters a long road to recovery.
Dareus (hamstring) was a limited participant in Wednesday's practice.
Dareus will look to get back to full participation by the end of the week with a tough matchup against the Patriots on Sunday approaching. Fellow nose tackle Corbin Bryant is also dealing with an ankle issue, so Dareus could see quite a large workload given he's ultimately able to play.
Woods (foot) practiced on a limited basis Thursday for the second straight day.
Things are starting to look hopeful that the wideout can return this week against the Patriots, and the Bills could certainly use him, with Sammy Watkins and Greg Salas out, and LeSean McCoy and Marquise Goodwin looking dicey.
Williams signed with the Steelers' practice squad Wednesday.
Williams was let go by the Bills after he showed up this summer grossly out of shape and then received a four-game suspension for a violation of the NFL's substance abuse policy. However, he did score nine touchdowns for the Bills last season, so putting him on the practice squad and seeing what he can do seems like a good low-risk signing by the Steelers. Still, some other team could pluck him off there pretty quickly.
Reddick, who suffered a sprained MCL in practice Friday, was waived/injured by the Bills on Sunday.
The Bills didn't have much choice here with several other linebackers injured and reinforcements needed. If Reddick clears injury waivers, the Bills can then either place the him on IR or agree to an injury settlement with him.
Coach Rex Ryan said Monday that Listenbee, a sixth-round rookie out of TCU, still isn't ready to practice as he recovers from double hernia surgery, The Buffalo News reports.
Even though the Bills have been decimated at wideout all season, there's simply not going to be enough time for this year to be anything more than rehab and learning for the speedy rookie, who's incredibly raw but may also be one of the NFL's fastest players once he's back.
