Mixon (knee) practiced fully Friday and doesn't carry an injury designation heading into Sunday's game against the Dolphins, Katherine Terrell of ESPN.com reports.
Mixon's return to the mix couldn't come at a better time with Giovani Bernard (knee) having been ruled out for Week 5 after filling in for Mixon as the starter the past two games. With his health in order, Mixon is thus poised to head the Bengals' backfield this weekend, with Mark Walton on hand to serve in a backup capacity.
