49ers RB Christian McCaffrey was limited in practice today, but HC Kyle Shanahan said he has had “no pain”, an encouraging sign for his availability Sunday.

If the 49ers had a commanding lead in the NFC West, there's a pretty good chance they would be more willing to ease CMC back into the gameplan, but at 4-4, they are not really in a position to mess around here. If McCaffrey is good to go, we should consider him an RB1 in Week 10.

Ian Rapoport is reporting the 49ers are still targeting Week 10 for RB Christian McCaffrey's return.

The Niners have a bye in Week 9 and we reported last week it was looking positive for CMC to return to the field for Week 10, which is an early Sunday game at the Buccaneers. Rapoport has said CMC has been ramping up and so far there have been no setbacks, and that continues to be a target date. It's possible CMC is heavily involved in the pass game with all the injuries to the Niners WRs up to this point.

RB Jordan Mason (shoulder) was in a blue jersey, I'm told.

Reports said Mason's injury wasn't considered too serious, and it's a good sign he was back at practice, despite wearing the non-contact jersey. The Niners will host the Chiefs and what should be a fun game to watch in the later window of Sunday. If Mason can't go, look for Guerendo to pick up the slack after he carried 10 times for 99 yards in Week 6 after Mason left the game.

The NFL’s leading rusher, 49ers RB Jordan Mason, is believed to have suffered a sprained AC joint during Thursday night’s win at Seattle that is not considered serious, but he will undergo further testing today, per sources.

This doesn't give us a good lean on how much time he could miss (if any), but there's a good chance Guerendo gets a shot at leading the rushing attack after he put the game away with a 70+ yard run. We'll keep an eye on the situation, but hopefully, Mason isn't forced to miss too much time.

San Francisco 49ers star running back Christian McCaffrey has bilateral Achilles tendinitis, meaning he has it in both legs, per NBC Sports. McCaffrey recently went to Germany for treatment.

The 49ers said they expected to get a "better idea" on McCaffrey's status over the next few weeks. The team's plan was to ramp up his rehabilitation to "see how it responds." General manager John Lynch added that the team is aiming to "quiet down" the injury.

The story said Achilles tendinitis is described as "an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone," according to the Mayo Clinic. Some Achilles tendinitis can be treated at home, while more serious cases can lead to tendon tears that may require surgery. The story went on to say, until McCaffrey, the team and the medical specialists see how the area responds to more work, it's hard to make a call on when he will be back, if he does come back this season. NFL Media reported Sunday that McCaffrey should be back, at least, by early November, but the report of bilateral Achilles tendinitis could change things. For now, Mason remains the bellcow. He had 24 carries in Week 4 with Deebo Samuel getting two. Guerendo had a fumble on special teams and had just one carry in the game.

And to top it off, 49ers RB Christian McCaffrey is seeing a specialist in Germany regarding his Achilles tendinitis.

This doesn't sound good for CMC. Now owners can't help but wonder if McCaffrey will be back after missing his four games on IR. Mason has filled in well, gaining 5.2 yards per attempt with two touchdowns on the season. But at this point, with CMC seemingly a huge question mark, it may be time to pick up players like Guerendo and Taylor. Guerendo was the only other back to get carries in Week 3, running five times for 19 yards.

The 49ers are now considering placing Christian McCaffrey on injured reserve, which would sideline him this week plus three more games, Shanahan said.

While it's possible that the team brings in another back, they sure weren't opposed to giving Jordan Mason a phenomenal workload last Monday. As it stands, Mason is a must-rostered, must-start option for as long as McCaffrey is out.

49ers RB Christian McCaffrey (Achilles/calf) feels like a long-shot for Sunday against the Vikings.

Jordan Mason went nuclear as a last-minute start in Week 1, so he should be in fantasy lineups of McCaffrey misses again. Guerendo and even Patrick Taylor could be rotated in a little more in Week 2, but aren't worth fantasy stashes quite yet.

The 49ers will have wide receiver Brandon Aiyuk and left tackle Trent Williams against the Jets on Monday night, but they will not have running back Christian McCaffrey.

Jordan Mason, Patrick Taylor and Isaac Guerendo are the available backs for the Niners.

Definitely a shocker and likely a big blow to fantasy owners. According to the story, McCaffrey said on Friday that he had no doubt he would play and there was plenty of optimism from head coach Kyle Shanahan and General Manager John Lynch as well. McCaffrey missed most of the summer with a calf injury and is listed with an Achilles issue as well, the story said. Mason had a great camp and seemed to get a lot of attention from coaches this summer, and likely should get a bulk of the workload tonight against the Jets. Hopefully CMC owners backed themselves up during drafts by nabbing Mason. If Mason is still on your wire, he's worth picking up for any team in case CMC's issues are longer term. Taylor and Guerendo could get work for the Niners as well - if you're in a pinch losing CMC. From the Jets side, Braelon Allen and Israel Abanikanda could see touches behind Breece Hall.

Running back Elijah Mitchell went on season-ending injured reserve.

Mitchell can only play this season if the 49ers reach an injury settlement with him and waive him from injured reserve, the story said. Mitchell has struggled to stay on the field but when he has played he's certainly impressed. Mason has had a good camp, according to reports and the team has praised his running style so he'll backup CMC. The team traded up to draft Guerendo, so there's a good chance he has a role this season as well.
