San Francisco 49ers DE Nick Bosa is officially questionable for Saturday night's game against the Packers after suffering a concussion in the Wild Card win at Dallas. HC Kyle Shanahan said Thursday, though, that Bosa's chances of playing are "looking good," according to ESPN's Nick Wagoner. LB Fred Warner, meanwhile, carries no injury status into Saturday's game after hurting an ankle against the Cowboys.

The 49ers deemed LB Fred Warner (hamstring) doubtful for Sunday's game at Seattle. The only surprise there is that he has any chance of playing. Initial reports projected him to miss a week or 2 with the injury. Expect the Niners to be without their star LB, though. LB Dre Greenlaw (groin) has been ruled out. LB/S Marcell Harris (concussion) is questionable. The depleted LB corps helps the outlook for Seahawks TE Gerald Everett.

ESPN reports that the 49ers expect LB Fred Warner to miss 1-2 weeks with the hamstring strain he suffered in Sunday's win over the Vikings. Fellow LB Dre Greenlaw is day-to-day, Cam Inman of the San Jose Mercury News reports. That leaves Azeez Al-Shaair as the best bet to lead San Francisco LBs in playing time for the Week 13 clash with Seattle.

Niners LB Fred Warner left Sunday's game against the Vikings with a hamstring injury. Keiana Martin of the team website reports that Warner will have an MRI on Monday.

Niners LB Fred Warner (neck, shoulder) and CB Emmanuel Moseley (hamstring) are active for today's game against the Cowboys. Starting outside CB Jason Verrett is a surprise inactive, though, after coming down with an illness. Verrett's absence improves the matchup for Cowboys WRs Michael Gallup and Amari Cooper, who spend most of their time outside.

Niners LB Fred Warner (stinger) is questionable for Sunday's game against the Cowboys. He made it back to full practice participation Friday, though. We'll check Warner's status Sunday morning when the inactives come out. CB Emmanuel Moseley (hamstring) is questionable for the game as well. Like Warner, though, he progressed from 2 limited practices to a full Friday. Moseley missed the past 2 games but seems to be trending toward a return. Moseley has been a low-level IDP option most of the year.

Niners LB Fred Warner left Sunday's loss to Washington in the 3rd quarter. He passed a concussion check, but HC Kyle Shanahan said after the game that Warner sustained a stinger in the neck-shoulder area. We'll see whether that threatens Warner's Week 15 availability.

The 49ers on Wednesday activated LB Fred Warner from the COVID list. That makes him available to play the opener against the Cardinals, a matchup that allowed him 9 and 12 tackles in last year's 2 meetings. A top-10 LB in our preseason rankings, Warner belongs in your Week 1 IDP lineup. Dre Greenlaw, meanwhile, takes a tumble in our Week 1 LB rankings.

The 49ers have placed LB Fred Warner on the COVID-19 reserve list. It's not yet clear whether Warner has tested positive or merely been exposed to a COVID-positive person. If Warner displays symptoms, his Week 1 availability would be in jeopardy. Other players have come off the list in as little as a day or 2. We'll keep an eye on the star LB's situation as the opener approaches. If Warner misses any games, Dre Greenlaw would likely take on a 3-down role.

NFL Network's Ian Rapoport reports that the 49ers have reached a 4-year, $54 million deal with LB Kwon Alexander. They can't finalize the contract until Wednesday afternoon. Alexander will join a LB corps that saw rookie Fred Warner play mostly on the inside last year. We'd bet on Alexander taking over the middle, though, and Warner playing the weak side. There's room for both to produce quality IDP numbers. Alexander is coming off a left ACL tear, but the new contract indicates little concern over his recovery. We'll certainly keep an eye on his progress through the spring and summer. We'll also see whether the Bucs stick with 2018 rookie Adarius Taylor at MLB or go in another direction.

NFL Network's Mike Garafolo reports that the 49ers will keep rookie Fred Warner at MLB today against the Chiefs and start Reuben Foster and Malcolm Smith at the OLB spots. Foster is returning from a 2-game suspension, while Smith missed the 1st 2 games with a hamstring injury. It remains to be seen who the Niners will keep on the field for passing sub packages. IDP owners can use Warner and Foster in Week 3 lineups, but be aware of the lingering playing-time question if you're facing tough starting decisions.

The 49ers got LBs Malcolm Smith and Reuben Foster back on the practice field Wednesday. Smith didn't even appear on the injury report, putting in a full workout after missing the 1st 2 games with a hamstring injury. Foster, meanwhile, completed his 2-game conduct-policy suspension and is eligible to return against the Chiefs this Sunday. HC Kyle Shanahan said Wednesday the coaches haven't decided on a plan for their LBs yet. The performance of rookie Fred Warner through 2 weeks complicates the decision. We'll watch for word from the coaches through the week. If we don't gain clarity before Sunday, though, it'll be tough to trust any Niners LB in IDP lineups.

Niners LB Malcolm Smith (hamstring) is inactive for the 2nd straight game. He entered the weekend questionable but appeared in only 1 practice this week -- a limited Friday workout. If rookie LB Fred Warner puts up another big game -- filling in for Reuben Foster in the middle -- Smith might not find a starting job available once his hamstring allows him to return.

Niners LB Reuben Foster was in uniform for Thursday night's preseason finale, indicating that he has cleared the league concussion protocol. He'll still miss the 1st 2 regular-season games because of a conduct-policy suspension, but Foster should be good to go after that. Rookie Fred Warner appears likely to start in Foster's place and carries attractive long-term upside for dynasty leagues.
