By Chris Williams: Unbeaten Floyd Mayweather Jr. (42-0, 26 KO’s) will be back in action on May 5th, according to Dan Rafael as ESPN. Leonard Ellerbe, Mayweather’s adviser, is saying that Mayweather will be fighting on the 5th of May in Las Vegas.

Here’s what Ellberbe said: “Floyd made it very clear that he wants to give the fans the biggest fights that are out there. He wants to stay active. We’re going to do everything in our power to make the biggest fight out there for the fans and we know what that fight is.”

That sounds promising, right? Not necessarily. Mayweather has had rotten luck in setting up a fight with Pacquiao n the past, mostly because of an inability to get Pacquiao to agree to the random blood tests that Mayweather wants before he’ll choose to fight him. There doesn’t appear to be any movement in this area from Pacquiao’s team, so it’s probably pointless for Ellberbe to even mention the Pacquiao fight. It would certainly be a great fight, but without Pacquiao staying in the United States during his training camp so that he can be tested by the USADA, we’re getting excited for nothing.

Mayweather has already made it clear that he wants Pacquiao to spend his entire training camp in the U.S so that he’ll be available for the testing the entire time, not just for the tail end of his training. There’s going to have to be movement in this area from Pacquiao and his management before this fight can be put together. Do I think that will happen? When pigs fly. As such, look for Mayweather to be fighting someone else in May, while Pacquiao fights someone from his promoter Bob Arum’s Top Rank stable.

Pacquiao is fighting Juan Manuel Marquez on November 12th in a third fight between the two. After that, Pacquiao could face either Mike Jones or Timothy Bradley, both of which are Top Rank fighters. Those fights will use up most of 2012. I don’t see where Mayweather comes into this picture, not when Pacquiao is continuing to spend half his training camps in the Philippines.
