I'm almost 100% sure that Stevie Richards is currently working for TNA wrestling. Backstage on tonight's iMPACT episode Abyss Cut a promo backstage with a man he referred to as "Dr. Stevie". He has also been referenced before in previous episodes of iMPACT.
Also Personally I've watched multiple Stevie Richards interviews and promos of him, He was also one of my favorite ECW wrestlers, basically saying i know that voice. I can almost bank on it.
