Former Broncos/Dolphins RB Knowshon Moreno is nearly done with football as his knees are just too bad. For the Dolphins, Moreno had a great opener rushing for 134 yards. However, he suffered a dislocated elbow in Week 2. On his bounce back in Week 3, he suffered a torn ACL. This came after severe knee injuries in Denver as well. Moreno plans to keep himself in shape as he’s waiting for “the call.” But for Moreno, reality is setting in that he may never receieve that call.
