Team news: San Francisco 49ers | Page 4

49ers WR Brandon Aiyuk left Sunday’s game against the Chiefs with a potentially significant knee injury.

Aiyuk was carted off the field after taking a big hit to his right knee. Deebo Samuel also left the game, meaning the 49ers are now currently without Aiyuk, Samuel and Jauan Jennings. They did just activate rookie Ricky Pearsall. The hope is the injury isn’t too serious but Aiyuk is going to miss a decent amount of time at the very least.

San Francisco 49ers are signing former Packers K Anders Carlson to their practice squad, source said.

Related players: Jake Moody, Matthew Wright

The Niners are adding some insurance after Wright injured his shoulder last week, the post went on to say. Moody is also dealing with an ankle injury, so it's possible Carlson is pressed into duty for Week 7.

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.

For TNF:
-- 49ers TE George Kittle (ribs) and LB Fred Warner (ankle) were full participants and will play.
-- The team promoted TE Brayden Willis to the 53-man and put S Talanoa Hufanga on IR.
-- Seahawks ruled out DT Byron Murphy II and CB Riq Woolen, while there is optimism for Boye Mafe and Derick Hall to play.

Kittle finds himself in a fantastic spot against the Seahawks, who rank 30th in TE aFPA. Fire him up everywhere you can.

The 49ers have found a kicker to replace the injured Jake Moody.

Per multiple reports, San Francisco has signed Matthew Wright.

Wright, 28, had a short stint with San Francisco’s practice squad early last year, though he did not appear in a game.

Moody is dealing with an ankle injury and there is no word how long Moody could be out. Wright should be a decent kicking option for fantasy lineups given the overall potential of the Niners offense. San Francisco is at Seattle on Thursday night.

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.

49ers TE George Kittle (hamstring) sounds like he expects to return on Sunday against the Patriots. Says he's "very excited to play football" and "feeling fantastic."

With Deebo Samuel more or less in the same boat, the 49ers are looking forward to getting some reinforcements after a brutal stretch of injuries. Kittle would be an absolute must-start if he returns in time for Sunday.

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 ruled TE George Kittle out for Week 3 against the Rams with a hamstring injury.

Kittle was initially listed as doubtful on Friday. Another big injury to a 49ers offense that is also without Christian McCaffrey and Deebo Samuel. Eric Saubert and Jake Tonges are the next men up. Both rank outside our top 30 tight ends this week.
