Mitchell (shoulder) practiced in a limited fashion Wednesday, Nick Wagoner of ESPN.com reports.
After sitting out Week 3, Mitchell logged limited sessions during Week 4 prep, but he donned a non-contact jersey in each one and was deemed inactive this past Sunday against the Seahawks. It's unclear if he ditched the blue jersey, as expected, but he may just be ramping his reps this week as he puts his shoulder stinger further in the rearview mirror. Mitchell has two more practices to go to bump up to full activity, at which point the 49ers will have a better indication of his status for Sunday's game at Arizona. Assuming he suits up, it'll be interesting to see the breakdown of backfield work between Mitchell and Trey Sermon, who has logged two straight starts in the former's absence.
