I think that Sword had bulging discs. I do not know what surgery he had done, but I am guessing it was the microdiscectomy, which removes a piece of the disc to release the pressure against the nerve. You don't come back easily from those. Ask Chaz Ramsey and Jarod Parks. You can come back easily to a normal day-to-day life but playing college athletics is a different story. I thought this earlier when I saw his surgery but did not mention it due to not knowing the whole story. If it is as I suspect, he won't be back this year.
