SANTA CLARA — Here is the 49ers’ roll call ahead of Wednesday’s practice and which injured players can and can’t play:
Elijah Mitchell (concussion/knee): He got placed in the NFL’s protocol Monday and that is only part of why he will not practice today. Mitchell also has knee “irritation,” coach Kyle Shanahan said Wednesday of an MRI result. As for the concussion, Mitchell must pass a series of tests this week to get cleared for Sunday’s game at Cincinnati.
This is the first time that Mitchell has had a knee issue listed on the injury report, though he wore a support sleeve on his leg last week in practice. Since camp, he’s also dealt with injuries to his adductor, shoulder, ribs (front and back) and right, middle finger.
Jeff Wilson Jr. (knee): His surgically repaired knee “flared up” Sunday and is expected to practice in limited fashion.
JaMycal Hasty (ankle): He’s recovered well enough from a pair of high ankle sprains that he could make his first career start Sunday, though Wilson likely gets dibs if fully healthy. “He got a lot better this year. Had a heck of a camp,” Shanahan said of Hasty. “When Raheem (Mostert) went down, he solidified himself as a third-down back, then had a high ankle sprain, then got another one. Last week was his first practice back. Hopefully he’ll continue to get healthier.”
Brian HIll: He was signed to the practice squad after Tuesday’s tryouts with two other running backs, and Shanahan cited Hill’s playing experience (36 games the last three seasons with Atlanta) as a driving factor in case he is needed to fill in Sunday (No. 48 jersey).
Trenton Cannon (concussion): He will not practice. He got discharged from a Seattle hospital and flew to the Bay Area on Monday, after a frightening injury on Sunday’s opening kickoff.
Deebo Samuel (groin): His Nov. 28 groin strain kept him out of Sunday’s loss in Seattle and it continues to keep him from practicing, though Shanahan hopes that changes Thursday. Samuel looked ready for that judging from how he ran on the side Wednesday.
Fred Warner (hamstring): He will be a full participant. Sunday’s loss marked the first game he’s missed in his four-year career. Warner initially lobbied to play last game before reconsidering. “We all talked about it and were on the same page, that the risk outweighed the reward,” Warner said. “It was go out and risk being out another four weeks, or take one week off and be back this week.”
Although he praised how well Azeez Al-Shaair played the “Mike” linebacker in his place, not participating was not enjoyable. “It was terrible,” Warner said. “I pride myself on being available for this team and … the streak was good while it lasted.”
Marcell Harris (concussion): He is cleared for full action after missing last week’s practices and Sunday’s game.
Dre Greenlaw (groin): He remains out after aggravating a core-muscle issue.
Dee Ford (back): Shanahan hopes he will resume practicing Thursday. He is two weeks into his three-week window to get activated off injured reserve.
Mo Hurst (calf): He remains out after experiencing a setback last week.
Emmanuel Moseley (high ankle sprain): He will not practice and is expected to miss the next few weeks.
Tony Jefferson: He was released from the practice squad to create room for Hill.

SPECIAL TEAMS ISSUES
Special teams coordinator Richard Hightower took full responsibility for the 49ers allowing a fake punt to go for a Seattle touchdown on Sunday’s first series of a 30-23 defeat.
“That’s totally on me. They had the perfect play on and they got us. The players couldn’t have done anything in that situation,” Hightower said. “They took a huge risk and got a huge reward. Most people don’t do that in that situation. It’s totally on me.”
As for another special-teams gaffe — Travis Benjamin’s fumbled kickoff return — Hightower didn’t rail Benjamin for not carrying the ball in his left arm closest to the boundary, rather than expose it easier to Nick Bellore’s fumble-forcing hit. “I’ve got to coach him better and get the ball in his other arm, and even if it is, he has to hold onto the ball,” Hightower said.
Wednesday’s practice will include extra drills about tackling and coverage on kickoff returns. “We’ve had two weeks in a row not up to our standard, and we can’t have that if we want to go where we want to go,” Hightower added.
Jimmy Garoppolo said he has “my own system” to review games, to see where he made the correct read and where he missed. What stuck out most to him about Sunday’s loss was the second interception he threw, saying he “got greedy.”
Garoppolo will be making his eighth straight start Sunday after missing a loss at Arizona because of a calf contusion. He hasn’t had to address his health since then. But he was asked Wednesday about how a pinkie injury could impact Bengals counterpart Joe Burrow.
“Anything on your right hand all comes into play, just differently,” Garoppolo said. “It could affect his spiral. Depends how seriously it is. It could affect how the grip on the ball, and in these colder games, it could play a factor.”
Garoppolo came one completion away — a fourth-down pass breakup — from setting the 49ers up for a potential game-winning, two-point conversion at Seattle. Shanahan said he would have gone for two points than a game-tying, point-after kick, to which Garoppolo said Wednesday: “I had a pretty good idea we’d go for two. We had the momentum. I had that feeling.”
