Many within WWE are very concerned about The Undertaker’s body and how much longer he can wrestle. WWE’s World Heavyweight champion is a shell of his former self these days, clearly in pain as he moves around and no longer possessing the agility that has made him such an impressive “big man” wrestler over the years. After the WrestleMania classic he and Shawn Michaels put on last year, its believed that Shawn Michaels will have to do a great deal of bumping around to save this year’s rematch from being a total letdown.
