Mixon (concussion) was listed as a full practice participant Wednesday, Ben Baby of ESPN.com reports.
Mixon put in a full practice for the first time since suffering the concussion in the Bengals' Week 11 win over the Steelers. The team hasn't yet confirmed that Mixon has cleared the NFL's five-step concussion protocol, but in the absence of any setbacks in the coming days, the Bengals' top back looks to be trending toward a return to action this Sunday against the Browns.
