According to a new report by ProWrestling.net, Hulk Hogan underwent back surgery last week leaving his status for a possible appearance or match at WrestleMania 25 highly unlikely. Hogan announced in February that he spoke with Vince McMahon, but they two were unable to agree on a WrestleMania appearance. It should be noted that the Twitter posts attributed to Hogan recently that generated some onlinze buzz were actually written by an impostor.
