Floyd Mayweather in WWE. Pretty exciting, and boy will that mean Money!

For those of you that didn't see No Way Out, I expect you know by now that Floyd Mayweather got involved in the Big Show's return.

As Show hoisted the injured Rey Mysterio in the air for a chokeslame, Floyd ran to the ring, hopped over the ropes and got in Show's face.

After some typical jostling of entourages etc, Big Show went onto his knees to give Mayweather a free shot. And the man known as Pretty Boy, the WBC Welterweight Champion, landed at least two clean blows to Big Show's face. Show chased Floyd & co away as Shane McMahon appeared to try to placate Big Show.

The above is not a wrestling commentary. It is genuine account fo what happened. Mayweather hit Show legit, and while I don't think for a second it wasn't planned, I do think that when Show appeared in front of the camera with a bloody nose and mouth that it was a hardway piece of juicing.

So what now? Perhaps this was a one shot event, although I doubt it. Mayweather is a huge deal, and possibly the biggest name in World Boxing right now.

This is not Pacman Jones. This is much bigger, and is, like, so totally Wrestlemania, dude.

Initial thoughts were a boxing match between the two. Boxing has been done before at Wrestlemania. One with Roddy Piper v Mr T (work) and once with Butterbean v Bart Gunn (shoot, and an embarassing one at that). We have also seen Sumo at Mania, with Big Show taking on Japanese Sumo star Akebono (work). Also, don't forget the involvement of a huge sports star in a main event at Mania - see Lawrence Taylor at Wrestlemania 11.

WWE may choose to go down the Pacman route, and make Mayweather's contest a tag match. This is a traditional method of involving celebrities, from Jay Leno to Dennis Rodman in WCW, and has been reported as the most likely method seeing Mayweather in the ring, sans big red gloves.

So how would the match pan out? Well, with Show on one side, his partner could very likely be Shane O Mac himself. For the purposes of making the bout look even, if Show's partner was Umaga or someone pretty tough, it would make Mayweather's involvement seem less plausible.

Especially since Floyd's partner might be lined up as Rey Mysterio. This, of course, may be in jeopardy, thanks for Rey's bicep tear. So if we have Big Show and Shane McMahon on one side, and assume that Mysterio cannot join up with Money Mayweather, who is going to step up? I have the perfect answer.

John Cena.

Its perfect. Cena didn't win the title last night, and although the rumoured Mania main event of Triple H v Cena v Orton could still be in the works, its not an essential component. You can take Cena out and still have a reasonably intriguing contest, no matter what the Hunter-haters may think.

If Cena is not in the title match, then I fail to see how any other match can be big enough for him at Wrestlemania if it is not something like this. Cena is by far and away WWE's biggest and most marketable star, no matter what people think of his in-ring ability. He would be able to carry the feud vocally, he always steps up for big matches, and this would give him the extra mainstream publcity, alongside Mayweather, that he would surely crave.

Rey might be semi-fit and try to gut this one out, as he did last night, but a biceps tear will not heal in 42 days, and I can't see Mayweather being able to carry this one alone if Mysterio does not make it.

If he cannot, then there would be no better replacement than John Cena.
