One of the most tenured performers on the WWE roster, Hardcore Holly, may be done as an active professional wrestler. Holly, who was slated to return to the Smackdown brand, is having continued issues with his arm stemming from his most recent surgery. The word going around at TV is that his condition worsened after the surgery and he’s having problems with feeling in the arm. The blame was being put on the doctors. Holly has been with the company since December 1993 when he debuted as Thurmann “Sparky” Plugg, the racecar driver. His name was later changed to Bob “Spark Plug” Holly before he finally morphed into Hardcore Holly during the Attitude Era.
