According to ESPN's Field Yates, the San Francisco 49ers worked out several running backs. They are Jeremy Cox, Brian Hill, and Dexter Williams.
The 49ers have one healthy running back entering Week 14's matchup against the Cincinnati Bengals. Starter Elijah Mitchell and Trenton Cannon are in the concussion protocol. Jeff Wilson Jr.'s knee flared up on Sunday against the Seattle Seahawks. Trey Sermon is on injured reserve due to an ankle injury.
That leaves JaMycal Hasty as San Francisco's only healthy running back.

On Monday, head coach Kyle Shanahan was asked if the team planned to work out any running backs because of the injury issues.
"Yes, I think those guys are working on that today (Monday), and hopefully, we'll get some more guys in here tomorrow (Tuesday) to work out," Shanahan responded.
The 49ers could announce the signing of one or more of these players soon, assuming the workouts went well.
Mitchell and Cannon's concussions occurred during Sunday's game.
Said Shanahan of Mitchell: "He was cleared after being evaluated during the game and post-game, but he had symptoms this morning, so he's in the concussion protocol."
Cannon's injury occurred during the opening kickoff. The running back and returner was transported by ambulance to a local hospital for evaluation.
"He's doing better," Shanahan said on Monday. "He's been discharged from the hospital, and he's flying home right now. Our doctors will continue to monitor him."
