The official rules have just been announced for the battle between Big Show and Floyd “Money” Mayweather at WrestleMania XXIV, though above all else, one fact will be made certain this Sunday night: There MUST be a winner in this match.

The only way one of these two warriors can earn a victory at The Granddaddy of Them All is by pinfall, submission or knockout. Anything goes in this historic match-up between WBC welterweight champion Mayweather, and former WWE, ECW and WCW Champion Big Show.

With Big Show standing 7 feet and 441 pounds – nearly three times the weight of the 5-foot-8, 159-pound Mayweather – not to mention the nearly one-foot difference in arm reach, their physical disparities are more than evident. With no rules, however, this personal rivalry is now anybody’s game for the taking in Orlando’s Citrus Bowl.

The Greatest Fighter in the World is quick to point out that very fact, saying, "Hey, what I do for a living is take risks. This is my idea that anything goes. He can’t beat me at my game, but I can beat him at his."

Big Show sees things much differently than Mayweather -- and not just because he's the World's Largest Athlete. "This guy made the mistake of entering my world in the first place. Now that I have agreed to these wide-open rules, I may just break his back," he said. "This is my world, not his."

Will Big Show use the rules, or lack thereof, to deliver on his promise to end the career of Floyd Mayweather? Or can “Money” cash in on a way to bring down the Big Show in front of 70,000 of our fans? The answer will become clear this Sunday night at WrestleMania XXIV, LIVE and on pay-per-view, at 7 p.m. ET/4 p.m. PT.
