The doctor working for the Cowboys is a non-factor to me. The doctor must be very optimistic or Dallas wouldn't have drafted him. There is no scientific test available that can determine about nerve damage and nerve healing. There are test that can detect the damage , but there is absolutely no way of knowing if the nerve will heal and be the same as it was before. I hope he has a 100% recovery, but it is not written in stone. Smith may have lifelong complications from the nerve damage. I know some posters are going to say that it was not damaged, but stretched. Stretching the nerve does damage it. If the nerve wasn't damaged, he would be ready to play now because the knee itself is healed. I have nerve damage in several nerves myself due to injury and the surgery. Smith may have lifelong numbness, burning, tingling, etc. In my case the different sensations come and go. Other people are different. In some cases it my be permanent. He may have minimal problems that allows him to play, but limits his ability. In other words, he may never play at his pre-injury level. It looks encouraging for Smith right now, but him returning to 100% is far from certain.ball we can do is hope for the best.
