49ers say WR Brandon Aiyuk (hamstring) week-to-week

The Raiders used up their temporary practice squad elevations for running back Sincere McCormick, so they made a more lasting roster move on Tuesday.

McCormick has been signed to the 53-man roster in Las Vegas. Wide receiver D.J. Turner was placed on injured reserve in a corresponding move.

McCormick played in the last two games for the Raiders as they were missing Mattison and White due to injuries. McCormick ran 12 times for 64 yards in last Friday’s loss to the Chiefs and he had five carries for 33 yards against the Broncos in Week 12, the story said. McCormick led the way for the Raiders against the Chiefs with 12 carries to Abdullah's 10. McCormick may be worth a pickup and stash at this point, as the Raiders are trying to figure out their roster for 2025. Mattison, White and Abdullah don't necessarily offer much future upside at the position, so it's possible the team will see what they have with McCormick going forward. However, keep an eye on the injury statuses of Mattison and White. The Raiders are at Tampa Bay in Week 14.

Austin Ekeler's response when asked whether he could return this season:

"It's week to week. I want to continue to learn more. It's my second concussion (this season). Am I more susceptible to a third now that I've had two and the severity of mine? It's a learning process for me because I've never had anything this bad and twice in the same season. ... The best thing about is the team has my back ... I really appreciate DQ (Dan Quinn) and Adam Peters for being there."

It doesn't seem like Ekeler has a timetable and the week to week tag indicates it could be some time. Ekeler is clearly concerned about this long-term well-being. From a fantasy angle, Robinson should continue to lead the way with McNichols seeing the passing down work. Rodriguez may be a guy to pick up in deeper leagues as a stash, especially if Ekeler ends up missing significant time. Rodriguez got some mop-up time and ended up carrying the ball 13 times for 94 yards, adding a touchdown in the fourth quarter against the Titans.

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.
