Mixon (foot) was listed as a non-participant at Wednesday's practice, Jay Morrison of The Athletic reports.
The Bengals haven't provided much of an update on the severity of Mixon's foot injury, but a return to practice in any capacity Thursday would brighten his Week 7 playing prospects. If, however, Mixon ends up limited or out this weekend against the Browns, Giovani Bernard would be in line to see added work, with Samaje Perine in line for top backup duties.
