RB Elijah Mitchell is in the concussion protocol, 49ers coach Kyle Shanahan said.

Mitchell took a nasty hit to the head against the Seahawks but eventually was cleared to come back in the game. Reports say Mitchell started to suffer some symptoms Monday, however. The Niners are at the Bengals in Week 14, and this game was moved from an early game to a later Sunday game. If Mitchell can't go, Hasty and Wilson are up next, but Wilson's knee flared up, according to the team, so his status is also in question heading into Week 14.

Nothing changes from their expected statuses earlier this week.

49ers coach Kyle Shanahan with following injury updates:

WR Deebo Samuel (groin) -- It's a strain. Expected to miss 1-2 weeks.

Samuel will miss Week 13, an away game at Seattle, but the team hopes to have him back for Week 14, an early game at Cincy. The good news is owners will have time to adjust lineups if he's a game-time call in Week 14. Samuel had been seeing more work as a runner so Aiyuk and Jennings likely lead the way as receivers while Mitchell and Wilson should eat up Samuel's carries.

The good new is, it’s not considered a major injury, the source said. Samuel was used more as a runner in Week 12 so this may not even create more targets for guys like Aiyuk, Sanu and Jennings. But, it may get Mitchell and Wilson more rushing opportunities. Wilson had just two carries while Mitchell went for 27-133-1 while adding five catches for 33 yards. Owners should probably figure on Samuel missing at least Week 13, with the hope of him returning for Week 14, or at worst, the fantasy playoffs.

49ers RB Elijah Mitchell (ribs, finger) is questionable for Week 12's game against the Minnesota Vikings.

Mitchell could be a game-time decision. If he does play, it would not be surprising to see him only run the ball because of his finger surgery.

Against an inferior opponent, it is best to give Mitchell another week to heal from finger surgery. Look for Wilson to be the lead back Sunday.

49ers RB Elijah Mitchell had a finger fracture. He's going to get it fixed but unclear just yet what his status for this week will be against Jacksonville.

Wagoner went on to say in another tweet that Shanahan said doctors are "pretty optimistic" Mitchell will be OK. And there's a chance Mitchell will be able to practice Wednesday. Wagoner added the team just wants to see how he's doing after getting pin put in finger during procedure. The Niners play the Jags in Week 11, so if they assume they can win the game, maybe sitting Mitchell a week makes some sense. Wilson saw limited snaps behind Mitchell in Week 10 and would likely get a bulk of the work if Mitchell has to miss time. There could even be another Trey Sermon citing if Mitchell is out.

Shanahan said kicker Robbie Gould and running back Jeff Wilson are set to work.

Gould’s been on injured reserve with a groin injury and Wilson is on the PUP list with a knee injury. Wilson’s extended time out of action could delay his return to the active roster, the story said so Mitchell should continue to get the bulk of the work for now.

Shanahan said Elijah Mitchell emerged from the game with a rib injury. Said the rookie runner will be limited in practice on Wednesday.

It seems like Mitchell should be able to play in Week 9 at home against the Cardinals. Hasty got just three carries last week for four yards but reports say Wilson could be back to practice this week as well. The 49ers play a late-afternoon game in Week 9 so owners should probably try to come up with a backup plan just in case Mitchell trends downward this week.

49ers HC Kyle Shanahan told reporters Wednesday that RB Jeff Wilson (knee) is still a few weeks away from being activated from IR.

This is expected and will only muddle the 49ers backfield.
