Mixon (foot) wasn't spotted during the open portion of Friday's practice, Ben Baby of ESPN.com reports.
With that, Mixon doesn't seem likely to suit up Sunday against Washington, though his status won't be officially known until the Bengals release their final Week 11 injury report later Friday. In any case, Giovani Bernard looks set to handle a three-down role this weekend, with Samaje Perine expected to serve as his top backup.
