The Los Angeles Times has an article up at this link discussing the possibility of a Hulk Hogan vs Roddy Piper match at WrestleMania XXX. The article references Piper’s tweets from yesterday where he teases the match on twitter.
One note on Piper’s tweets yesterday. There is a rumor online that the tweets are actually referring to Piper doing an interview with Mr. T. Piper and Mr. T have not been on good terms since the mid 80s so this would be a truce between the two. I haven’t been able to confirm that that though.
