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.
Heyward is expected to miss 2-to-3 weeks due to the hamstring injury he suffered Sunday, NFL.com's Aditi Kinkhabwala reports.
Heyward's injury is not considered serious, but the results of Monday's MRI unfortunately suggested it could keep him sidelined until Pittsburgh's Week 8 bye. That would mean missing Week 7's top-heavy tussle against the Patriots. A Steelers team captain, Heyward boasts 17 tackles, three sacks and a fumble recovery so far this season.
Roethlisberger (knee) did some individual work at Tuesday's practice, saying afterward that he hopes to rejoin his teammates at some point next week, ESPN.com's Jeremy Fowler reports.
Roethlisberger had surgery last Monday to repair a torn meniscus, with his estimated timetable of two-to-three weeks subsequently referred to as a "best case" scenario by Steelers president Art Rooney II, who said the real expectation is anywhere in the range of two-to-six weeks. Roethlisberger threw some passes to tight ends at Tuesday's practice, but it doesn't mean much that he's able to make throws while standing still. Real information regarding his potential Week 9 availability probably won't be available until next week. The Steelers are currently on bye ahead of a matchup with the rival Ravens.
Wheaton (shoulder) has been ruled out of Sunday's game against the Patriots.
Wheaton didn't practice after missing last Sunday's game due to a shoulder injury, which will cost him his fourth contest of the year this weekend versus New England. His continued absence figures to benefit Eli Rogers and Sammie Coates, although the latter wideout's fractured thumb could impact his involvement to some degree.
Williams (knee) has been ruled out of Sunday's game against the Patriots.
Williams' knee injury prevented him from practicing at all this week, so Le'Veon Bell should be prepared for an even heavier workload Sunday versus New England. In Williams' absence, Fitzgerald Toussaint embodies the Steelers' lone healthy running back behind Bell, who was already expected to see his usage increased in wake of quarterback Ben Roethlisberger's (knee) injury.
Bryant was never under consideration of being cut by the Steelers despite his recently imposed year-long suspension, the Pittsburgh Tribune-Review reports.
Bryant's multiple violations of the league's substance abuse policy triggered a minimum one-year suspension from the league, but the Steelers never considered releasing him, according to general manager Kevin Colbert. Instead, Pittsburgh will hope Bryant makes the necessary changes to his life to get reinstated next year, when he would have two years remaining on his contract with the team. With Bryant suspended, Steelers receivers Markus Wheaton and, more specifically, Sammie Coates, will be looked upon to take advantage of their increased opportunities this season.
