Mixon (concussion) practiced fully Wednesday, Paul Dehner Jr. of The Cincinnati Enquirer reports.

Mixon also practiced fully last Friday before being ruled out in advance of the Bengals' Week 15 loss to the Vikings, so it can't be assumed that he's cleared the NFL's concussion protocol just yet. That said, Mixon's continued full participation does bode well for his chances of returning to action Sunday against the Lions. Mixon had been working as the Bengals' lead back before missing the last two contests with the head injury, but he could be eased back into action in Week 16 and split snaps out of the backfield with Giovani Bernard.
