Greenlaw (Achilles) was designated to return from injured reserve Wednesday.

The 27-year-old linebacker has yet to play this season after tearing his Achilles in San Francisco's Super Bowl LVIII loss to the Chiefs. However, he'll return to practice in a limited fashion Wednesday, as coach Kyle Shanahan told Lindsey Pallares of the team's official site, and he now will have 21 days to be activated to the active roster or else remain on IR. Greenlaw has a chance to play in the Week 13 matchup against the Bills if he's activated before Sunday.

Lenoir (knee) will not practice Wednesday, Nick Wagoner of ESPN.com reports.

Lenoir knocked knees with another player last Sunday against the Packers and underwent an MRI on the knee Monday. The results of that MRI aren't yet known, but Lenoir's starting his practice week with a DNP. Isaac Yiadom and Rock Ya-Sin are the Niners' lone healthy cornerbacks at the moment.

Head coach Dave Canales said Wednesday that the Panthers don't expect Sanders (neck) to play Sunday against the Buccaneers, Darin Gantt of the team's official site reports.

Sanders was placed on a backboard and carted off the field just before halftime of this past Sunday's loss to the Chiefs after he landed on his neck as he was tackled at the end of a 10-yard catch and run. He was evaluated further at a Charlotte-area hospital before getting discharged not long after the game. Canales told Mike Kaye of The Charlotte Observer on Monday that Sanders avoided a serious injury before adding Wednesday that the rookie tight end may practice later this week. In any case, Sanders seems destined to be inactive Week 13.

Williams (ankle) will not practice Wednesday, Nick Wagoner of ESPN.com reports.

Williams missed the 49ers' Week 12 loss to the Packers. Jaylon Moore got the start at left tackle in his place and would likely handle those duties again Sunday in Buffalo if Williams is unable to play.

Bosa (hip/oblique) will not practice Wednesday, Nick Wagoner of ESPN.com reports.

Bosa missed last Sunday's loss to the Packers after he was injured in the Week 11 loss to the Seahawks. Sam Okuayinonu, Leonard Floyd and Yetur Gross-Matos paced the 49ers in pass-rushing snaps off the edge versus Green Bay and would likely do so again if Bosa is unable to play Sunday in Buffalo.

Walker (hamstring) has been ruled out ahead of Thursday night's matchup against the Packers, David Furones of the South Florida Sun Sentinel reports.

Walker is set to miss his first game of the season Thursday night after sustaining a hamstring injury sustained in the Dolphins' Week 12 win over the Patriots. Expect Tyrel Dodson to serve as one of Miami's first-team inside linebackers on Thanksgiving Day in Walker's stead.

Fuller (concussion) has been ruled out ahead of Thursday night's matchup against the Packers, David Furones of the South Florida Sun Sentinel reports.

The veteran corner was estimated as a non-participant in practice all week after missing the Dolphins' last two games due to a concussion, so it's no surprise he won't play in Miami's Thanksgiving Day matchup in Green Bay. Second-year pro Cam Smith and rookie Storm Duck are likely to see increased roles in the Dolphins' secondary while Fuller remains sidelined in Week 13.

Coker (quadricep) was a non-participant at Wednesday's practice, Darin Gantt of the Panthers' official site reports.

Coker was a late addition to the Panthers' injury report last Friday due to a quad issue that left him questionable for Week 12 action. He eventually was deemed inactive for this past Sunday's game against the Chiefs, and he now has missed two straight practice sessions as a result of the injury. Head coach Dave Canales told Joe Person of The Athletic on Wednesday that he doesn't expect Coker to be available Sunday versus the Buccaneers, something that may be confirmed by the time Carolina posts its final report of the week Friday.

Hill (wrist/personal) doesn't have an injury designation for Thursday's game at Green Bay, David Furones of the South Florida Sun Sentinel reports.

The Dolphins listed Hill as a limited participant Monday due to a lingering wrist injury before he was a non-participant Tuesday due to both the wrist issue and a personal matter. He was back with the Dolphins as a full participant for Wednesday's walk-through session, clearing up any concern about his ability to play against the Packers. Hill will be taking aim at a tough Green Bay defense after recording just five catches for 48 yards (on six targets) in a win over the Patriots last Sunday.

Head coach Kyle Shanahan said Purdy (shoulder) will be a limited participant at Wednesday's practice, Nick Wagoner of ESPN.com reports.

Purdy emerged from Week 11 with a sore right shoulder, and he eventually was ruled out for this past Sunday's loss to Green Bay, seemingly out of an abundance of caution. Shanahan told Nick Wagoner of ESPN.com that Purdy resumed throwing Monday, and the quarterback now seems to be on a path to returning to action Sunday at Buffalo. How Purdy is listed on practice reports Thursday and Friday likely will be key for his odds to play this weekend.
