From what I understand he's ahead of schedule with his rehab. But even with the nerve "sleeping", he's ahead of schedule with recovering from the nerve damage. If I read the reports right, he's hopeful to gain an inch of nerve recovery a month. The doctors told him not expect anything from the nerve for 3 months post operation. In early march he started getting feeling back and his knee is tinkling which is a good sign that the nerve will heal. From what I read and understand he started getting sensations in his knee before doctors expected him to. So it's looking pretty positive.
I wish I could read about his recovery from a non-biased source. Some sources I read from gives the impression he can play this year, some other non-cowboy sources say he won't play this year.
I wish the team doctor would hold a press conference about it, or do a write up about it. Jaylon says he'll play, he says he feels good, but all players say that. Fingers crossed
