OT Trent Williams (ankle)

Related Players: Patrick Taylor, Kyle Juszczyk, Israel Abanikanda

We're assuming Taylor will now be the next, next man up, but they also have Abanikanda, as well as Ke'Shawn Vaughn on the practice squad. Taylor should be considered somewhere in the RB3 range if Guerendo is out, but the others should just be on WW watch for now.

After losing RBs Christian McCaffrey, Jordan Mason and Elijah Mitchell to season-ending injuries, it now looks as if the 49ers will be without RB Isaac Guerendo for Sunday’s game vs. Miami. Guerendo is dealing with a hamstring injury and is unlikely to play, per source.

Sheesh. We're assuming Taylor will now be the next, next man up, but they also have Abanikanda, as well as Ke'Shawn Vaughn on the practice squad. Taylor should be considered somewhere in the RB3 range if Guerendo is out.

In Week 15, the red and gold have defensive lineman Nick Bosa and linebacker Dre Greenlaw active and ready for the team's second meeting with their NFC West rival, the Los Angeles Rams.

On the other side of the ball, the 49ers will have rookie running back Isaac Guerendo available against the Rams. He was listed as questionable on Wednesday on account of a foot sprain but was given the green light to play ahead of "Thursday Night Football."

We do expect Guerendo to handle the majority workload for TNF, but you do have to wonder if he gets the same type of workload he would have, had he avoided the injury report all week. Consider him closer to an RB3 than a locked-in RB2 he otherwise would have been.

San Francisco 49ers running back Isaac Guerendo plans to play Thursday night against the Los Angeles Rams despite his sprained foot, sources told ESPN's Adam Schefter.

Guerendo, who is listed as questionable, insists he "feels good," sources said.

We're projecting Patrick Taylor as the next man up in the 49ers' version of running back roulette *if* Guerendo is forced out, as he easily has the most familiarity with the team. Abanikanda can be stashed if that's not the case, but shouldn't be in starting consideration if Guerendo does indeed miss Week 15.

Otherwise, consider the fourth-round rookie a fantasy RB2.

— The 49ers ruled out LT Trent Williams (ankle) and S Malik Mustapha (chest), but RB Isaac Guerendo (foot) is questionable. So is Dre Greenlaw, who was full today.
— The Rams ruled out TE Tyler Higbee (knee) and Cobie Durant (chest).

49ers head coach Kyle Shanahan shared his team’s pre-practice injury report at a Tuesday press conference and it was the same as Monday’s estimated one, so several key players are on the sideline ahead of Thursday’s game against the Rams.

Among them was RB Isaac Guerendo.

Guerendo had a great game in Week 14, but left with a sprained foot. Guerendo said afterward he felt great and it was just precautionary. However, we know by now we can't always trust when a player talks about his status for the following week. The DNPs for both Monday and Tuesday are not a great sign for Guerendo's chances to play in Week 15, which is a short week against the Rams on Thursday Night Football. Guerendo's practice status for Wednesday will hopefully will give us a better idea. Taylor would likely be next up for the 49ers if Guerendo can't go.

Isaac Guerendo doesn't seem concerned about the foot sprain he suffered today.

Guerendo was having a great fantasy day and was the team's clear RB1 against the Bears before leaving with a foot sprain. There are a couple of reports out there, including this one which comes from the Mercury News, saying Guerendo leaving was just precautionary, and that he "feels great." Other reports don't necessarily mention that. Hopefully we'll learn more today. What complicates this injury is the Niners take on the Rams on Thursday night, so it's a short week. We'll at least learn more as the practice week goes on. If Guerendo can 't go, Taylor is up next with newly-signed Abanikanda after that.

The 49ers were down to one healthy running back on their active roster, so they added another one off the waiver wire on Tuesday.

The NFL’s daily transaction report shows that they have claimed Israel Abanikanda off of waivers from the Jets. Abanikanda was let go on Monday when the Jets signed running back/kick returner Kene Nwangwu to the 53-man roster.

Christian McCaffrey was officially moved to injured reserve in a corresponding move.

Guerendo is expected to take over the team's RB1 role with Christian McCaffrey and Jordan Mason both heading to IR. Abanikanda should be a familiar name to those in dynasty circles. He was a 2023 fifth-round pick but at the time was buried on the depth chart with the Jets, and he never earned much of a role on offense and didn’t play in the regular season this year, the story said. He appeared in six games as a rookie and ran 22 times for 70 yards while catching seven passes for 43 yards, the story added. The team also signed Vaughn to their practice squad.

Braelon Allen, a 2024 fourth-round pick, wasn't known for his receiving in college -- only 49 catches in three seasons at Wisconsin -- but he demonstrated plenty of ability in OTAs and minicamp. He showed excellent ball skills and terrific body control. He's 235 pounds, yet he was able to split out and play like a smaller back. "If you go back and watch his tape at Wisconsin, he caught the ball well," Jets running backs coach Tony Dews said. Allen has a chance to be Breece Hall's primary backup.

There was slight concern that Allen would only be a rotational goal line back but if he flashes some receiving skills, he could have slight standalone value. He's the back to keep an eye on if anything were to happen to Hall.

Jets are signing free-agent RB Tarik Cohen to a one-year deal. Cohen was one of the NFL’s top return specialists and a receiving threat before injuries derailed his career. Cohen last played in the NFL in 2020, but now will attempt his comeback with the Jets.

It feels like ages ago, but Cohen does have back-to-back 70+ reception seasons on his resume. If he can make the final roster, he could be able to take advantage of the new kickoff rules for the Jets. He shouldn't be considered a fantasy option at this point.
