Not sure how credible this is . . . but some of the analytical points are worth noting . . . .
"Recovery from nerve injury is usually early or not at all.
At this point medically, it appears there is no way for the nerve to ever be 100 percent.
Smith has blown through the reported recovery estimate already, as his doctor initially indicated a
three-month timeline from April of 2016. No question he had a top surgeon, who happens to be the Cowboys team doctor, but there is not much one can do about a nerve. It either does or doesn’t recover."
