The 49ers officially activated RB Christian McCaffrey from injured reserve Saturday.

McCaffrey will make his season debut Sunday against the Buccaneers after dealing with Achilles tendinitis since the preseason. McCaffrey isn't quite at the top of the board just yet, but he does slide into the top 10 among running backs this week against a middle-of-the-pack rush defense in Tampa Bay.

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.

Running back Christian McCaffrey is back on the practice field with the 49ers.

Videos from reporters showed McCaffrey on the field Monday, but any word on his participation level won’t come until Wednesday’s injury report is released.

Head coach Kyle Shanahan said last week that the plan was for McCaffrey, who has missed the entire season with an Achilles injury, to spend the bye week ramping up his work before joining the team at practice this week. That plan did not change and the 49ers officially opened his window to return on Monday, the story went on to say. McCaffrey can practice for the next 21 days before the team would reach a deadline to activate him, but Shanahan indicated that the hope was to have McCaffrey available against the Buccaneers in Week 10 the story added.

Reports say CMC is really planning to ramp up in order to be back for their Week 10 match at Tampa Bay. The bye week is certainly hitting at the right time and the team will be looking to see if he responds well to this week's hard work to simulate practice, the post added.

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.

Anyone who held on to Jennings should be in good shape as he will likely slide in as the team's WR2 behind Deebo. Jennings didn't play in Week 7 because of a hip injury but the team is hoping to have in back for Week 8, according to reports. Pearsall was active for the first time and caught three balls for 21 yards. Cowing had two catches for 50 yards. Both rookies could be options behind Samuel, Kittle and likely Jennings, but may not be consistent fantasy producers. We reported McCaffrey is looking to return on Nov. 10 and it's possible he's counted on as a receiver more than a rusher once he's back.

49ers RB Christian McCaffrey's target to return is early November. The Niners have a bye the first week of November, but November 10 could be a potential return date, according to Ian Rapoport.

Rapoport said CMC continues to ramp up. He's been running on flat ground and there is no reason to be pessimistic, and it's been all systems go up to this point, Rapoport said. It's good news for McCaffrey and a potential return. As far as fantasy goes, hopefully his owners are still alive for a playoff berth by the time we get to Nov. 10. It may not be fair to think CMC jumps right into his normal bell cow role his first game back. The team may opt to continue to use Mason, who has done a great job filling in. With the potential loss of Brandon Aiyuk, CMC owners shouldn't have much worry inserting him in lineups once he's back.

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 placing RB Christian McCaffrey (calf/Achilles) on injured reserve, per Adam Schefter of ESPN.

The 49ers had been leaning in this direction. They will now be without CMC for at least the next four weeks, meaning he will miss games against the Vikings, Rams, Patriots and Cardinals. He'll probably also miss a fifth game, as the 49ers have a short week after the Cardinals game before a Thursday night game in Week 6 against the Seahawks. Perhaps he can return for the Super Bowl LVIII rematch in Week 7 against the Chiefs. For now, it will be the Jordan Mason Show after his huge Week 1 performance against the Jets -- 28 carries, 147 yards.
