The Cincinnati Bengals could be without running back Joe Mixon for an undetermined period of time.
Mixon will undergo arthroscopic surgery Saturday to clean up the knee he injured in Thursday night's win against the Baltimore Ravens, NFL Network's Tom Pelissero and Mike Garafolo reported, via sources informed of the situation.
The timeline for Mixon's return won't be clear under after the procedure is completed, Pelissero and Garafolo reported.
Bernard should see feature back touches with Mixon sidelined and may have that sort of value for a full month if Mixon's recovery doesn't go smoothly. Consider Bernard a high-end RB2 while Mixon is out. Walton and Carson are next up on the depth chart.
