Mixon (ankle) didn't practice Thursday, Ben Baby of ESPN.com reports.
With back-to-back practice absences to start Week 5, Mixon will need to get back on the field Friday in order to have a chance to suit up Sunday against the Packers. If he ends up limited or out this weekend, Baby notes that Samaje Perine would be in line to see added carries, with Chris Evans a candidate to see an expanded third-down role.
