Johnson (concussion) was not listed on the Panthers' injury report Wednesday.

The second-year pro was inactive for the Panthers' Week 12 loss to the Chiefs after sustaining a concussion prior to the team's Week 11 bye, but his omission from Wednesday's injury report suggests he's cleared the NFL's five-step protocol. With Johnson now back to full health, he's expected to serve as Carolina's top backup outside linebacker.

Head coach Jim Harbaugh said Wednesday that Dobbins is "working through something with his knee," while adding that he expects the running back to "miss some time," Eric Smith of the Chargers' official site reports.

Per Kris Rhim of ESPN.com Dobbins suffered a sprained MCL in his left knee during Monday's loss to the Ravens, and as a result, the running back is expected to be out Sunday against the Falcons before being considered week-to-week beyond that. If Dobbins is indeed unavailable this weekend, Rhim indicates that Gus Edwards will likely get the bulk of the carries versus Atlanta. Meanwhile, reserve backs Kimani Vidal and Hassan Haskins would be on hand for change-of-pace work behind Edwards.

Doubs (concussion) has been ruled out for Thursday's game against the Dolphins, Wes Hodkiewicz of the Packers' official site reports.

Doubs suffered a concussion in the middle of the third quarter of this past Sunday's win against the 49ers when he drew a pass interference penalty in the end zone. He then was listed as a non-participant on all three practice estimates of Week 13 prep and thus won't be available Thursday. Dontayvion Wicks, Bo Melton and Malik Heath will be the candidates to see extra reps in three-wideout sets alongside Jayden Reed and Christian Watson. Meanwhile, Doubs' next chance for game action will come Dec. 5 at Detroit in another Thursday game.

Ingold (calf) has no injury designation ahead of Thursday night's matchup against the Packers, Marcel Louis-Jacques of ESPN.com reports.

Ingold upgraded to full participation in Wednesday's walkthrough after opening Miami's week of practice with consecutive limited sessions, suggesting that he's moved past his calf injury in time for Thursday night's game. The 28-year-old has appeared in nine games this season, logging nine carries for 13 yards and catching seven of eight targets for 60 yards. He's expected to contribute on offense and special teams in Week 13.

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.
