Mitchell (shoulder) is wearing a non-contact jersey at Friday's practice, Nick Wagoner of ESPN.com reports.
This is his third consecutive day in the jersey and likely the third straight day he'll be listed as a limited practice participant. Mitchell's availability for Sunday against Seattle remains uncertain, with a 'questionable' designation and game-time decision looking like a possibility at this point. It remains to be seen how the Niners list Mitchell on their final injury report Friday afternoon.
