Dunbar saw his 2015 season cut short in October when he suffered a major injury to his left knee against the New Orleans Saints, tearing the anterior cruciate ligament, medial collateral ligament and the patella tendon.
There is a chance he might not be ready for the start of the regular season, let alone the start of training camp and is a good candidate to put on the physically unable to perform list.

Fantasy Impact:
In theory, this helps the stock of Darren McFadden since he would serve as the team's primary passing down back with Dunbar sidelined.
