Walker has an ACL injury that will cause him to miss the entire 2016 season, Mike Klis of The Denver Post reports.
Walker was carted off the field during Monday's practice, and an MRI confirmed the worst case scenario. The veteran defensive lineman was projected to backup Derek Wolfe on the left side of the line this season. Calvin Heurtelou now figures to slide into that role.
Ware (undisclosed) has been removed from the non-football injury list and will practice on Tuesday.
It was initially announced that Ware would return to practice next week, but it seems the team decided to bring him back a bit sooner. The veteran linebacker has been medically cleared to play for a few weeks now, but the team has been keeping him out to allow him to rest so that he's fresh for the regular season. At this point he isn't expected to play in Denver's final two preseason games, allowing Shane Ray to continue to see snaps with the starting unit.
Talib (leg) is expected to play in Saturday's matchup with the Rams.
Talib began training camp on the non-football injury list after suffering a gunshot wound to the leg in June, and, though he's practiced, he has yet to play in a preseason tilt. He's unquestionably one of the team's top two corner backs and will start opposite Chris Harris during the regular season. It's yet to be determined if Talib will start on Saturday if he does indeed play.
When asked Sunday for a timetable for his return to full action, Mitchell -- who dislocated his left elbow on Aug. 11 -- said he didn't "have an answer for that," CSN New England reports.
On the plus side, Mitchell -- who has returned to the practice field in a limited capacity -- while sporting a large brace around his elbow, noted Sunday that he's "feeling good...feeling a lot better than the day it happened." Once he's able to play without restrictions, Mitchell could emerge as a candidate to claim the Patriots' "X" receiver role, but for now his early-season fantasy upside is somewhat stalled by his elbow issue. Beyond that, it may take some in-season injuries for Mitchell to merit lineup consideration, given that there are plenty of other options in the Patriots' passing attack, namely fellow wideouts Julian Edelman, Chris Hogan (and Danny Amendola to a lesser degree), as well as the team's talented tight end combo of Rob Gronkowski and Martellus Bennett.
Ninkovich, who tore his triceps on Aug. 9, was present at the start of Sunday's practice before moving on to the Patriots' lower field to do conditioning work, ESPN.com reports.
Initial Boston Herald reports suggested that Ninkovich's return would be a matter of "weeks, not months." While it's unclear when the defensive end might be able to practice fully, his presence on the field Sunday, in any capacity, is a positive sign nonetheless.
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.
Brady (suspension), who returned to the team Tuesday following an excused absence, downplayed the thumb injury he sustained in advance of last Thursday's preseason game against the Bears, ESPN's Mike Reiss reports.
Brady accidentally sliced his right thumb on a pair of scissors before the contest, and when asked about the injury Tuesday, the QB noted that his thumb feels "good" now, adding that "it took a few days. I wanted to go (Thursday) and Coach [Bill Belichick] said it's probably best if we just take it easy." Moreover, Brady put forth the notion that he would have played last Thursday if it had been a regular-season game. While his playing status for this Friday's preseason tilt at Carolina has not yet been determined, Brady's four-game suspension to start the coming season is clearly more relevant from a fantasy perspective than his thumb issue, which turned out to be minor.
