From US site PWInsider.com:

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 1995 when he debuted as Thurmann "Sparky" Plugg, the racecar driver.

YES!
I mean don't get me wrong, I wouldn't wish injuries on anyone (well...almost anyone) but the news that we will be rid of the one the world's stiffest, blandest wrestlers is nothing but a blessing.
