The much-ballyhooed fight between Floyd Mayweather and Manny Pacquaio will now be a “Falls Count Anywhere” brawl.

In an effort to spark a last-minute boost to pay-per-view buys, promoters of this weekend’s much-hyped boxing showdown between Floyd Mayweather Jr. and Manny Pacquaio have made the bout a “Falls Count Anywhere” match.

No longer confined to the four sides of the boxing ring, Mayweather and Pacquiao can brawl all over the the MGM Grand Garden — in the crowd, in the locker room area, and even outside the arena.

At a press conference this morning, Mayweather promised to “whup” Pacquaio “up and down the Vegas strip” and knock his opponent out with a pair of brass knuckles (a legal maneuver given the no-disqualification nature of Falls Count Anywhere matches).

Sources within Pacquiao’s training camp revealed that the Filipino star intends to perform a “balcony dive” onto Mayweather — a dangerous maneuver that Pacquiao learned from his hero and mentor, New Jack.

While fans can expect a wild and violent brawl from the two competitors, it is unlikely to a bloody encounter, since the World Boxing Federation (WBF) banned “blading” several years ago.

It is also unlikely that this weekend’s fight will be the final encounter between Mayweather and Pacquaio; backstage sources report that the men are already slated to square off in a Hell in a Cell match next month.
