TMZ.com are reporting that the reason Hulk Hogan is suing the Laser Spine Institute for $50 million is because his back problems cost him a WrestleMania 25 match against John Cena.  The report also claims that the match was supposed to be his last for WWE.

Cena ended up involved in the World Heavyweight Championship match with Edge and Big Show at WM25, while Hogan did not appear at all.  His last WWE appearance was at Raw’s 15th anniversary show.
