Dallas Cowboys running back Lance Dunbar will be on crutches for two more weeks before he starts full-bore into his rehab from surgery to his left knee. He said he will be 100 percent by the start of the Cowboys' offseason program in April. Dunbar suffered a posterior lateral corner injury in the fourth quarter against the Oakland Raiders on Thanksgiving. It also happened to be Dunbar's best game of the season, as he finished with 82 yards on 12 carries. "The doctors told me I should be fine, and I should feel like I didn't even have surgery," Dunbar said. "It's feeling good now. I can bend it; have full range of motion, so we'll see." In the four games after Dunbar's injury, DeMarco Murray got all but nine of the carries by a Cowboys' runner. Joseph Randle had nine carries for 53 yards in the blowout loss to the Chicago Bears.
