If WBO welterweight champion Manny Pacquiao defeats Joshua Clottey on March 13, and Shane Mosley retains his WBA title against Floyd Mayweather Jr. on May 1 - Top Rank's CEO Bob Arum is more than willing to make a Pacquiao vs. Mosley unification clash for the fall. Mosley recently told BoxingScene.com, that if he beats Mayweather in May, he would like to fight Pacquiao next - with or without a contract clause that calls for random drug testing. Mosley could care less about the tests. He just wants to get Pacquiao in the ring.

Arum is not surprised with Mosley's recent comments. When Mosley fought two of Top Rank's fighters, Miguel Cotto and Antonio Margarito, Arum never brought up Mosley's past and he made any demands for a contract clause that involved additional drug testing. Prior to the rematch with Oscar De La Hoya in 2002, Mosley inadvertently took performance enhancing drugs. 

"I love Shane Mosley. I wish him all the best. He is one terrific guy. Despite that problem in the past that he had with the drug use, when he fought two of my guys - Cotto and Margarito - I never ever said a word. Mosley's word, when he said he wasn't using, was good enough for me. Mosley has always been a gentleman and I have a great deal of respect for him," Arum told BoxingScene.com.

The situation is not same with Mayweather. Negotiations for a Mayweather-Pacquiao fight fell apart because the two fighters could not reach an agreement on the contract clause that called for random drug testing. Pacquiao had no issue with random urine tests, but he did have an issue with the random blood tests being administered too close to the fight date. He wanted the random blood tests to continue until 24-days before the fight. Mayweather wanted them to continue until it was 14-days before the fight.

Mayweather, should he beat Mosley, will not back away from his demand for random blood tests when it comes to a Pacquiao fight. Unless the governing commission calls for additional testing, Arum and Pacquiao will not agree to Mayweather's demand for the random drug tests.

"Our position is the same. Mayweather, Mosley or any other fighter can lobby the boxing commission for any additional drug testing. Boxers can't make this kind of decision on their own. If the commission, depending on where the fight takes place, issues a ruling, then that's another thing, but it has to be at the commission level," Arum said. 

"They have a new urine analysis that can catch HGH. Blood testing is too intrusive. When you go to doctor to get blood drawn, as mostly people do during a yearly physical, how many times has the nurse had trouble finding the vein and she continues to plug in and then your arm is sore and you can't use it for three days. If you are a runner, it doesn't matter but a fighter relies on throwing punches. Blood testing is not the answer."

"All of this testing is ignorance. I don't think Mayweather is taking anything. I don't think Mosley is taking anything. And I don't think Pacquiao is taking anything. It's all bulls**t. I think Mayweather just used it to get into Pacquiao's head."

Arum is still sore at De La Hoya over some of his past comments with respect to the drug testing drama that overshadowed the Pacquiao-Mayweather negotiations.

During the last few weeks, respected author Thomas Hauser has challenged De La Hoya to sign a waiver to disclose the full details of his drug testing history in the state of Nevada - and the waiver would also permit officials in Nevada to discuss De La Hoya's drug testing history on the record.

Keith Kizer, director of the Nevada State Athletic Commission, is disputing any claims that De La Hoya tested positive for steroids in the state of Nevada. Hauser says Kizer might learn a thing or two if De La Hoya signs the waiver. Arum brought up the 2002 grace period in Nevada, which Hauser wrote about a few weeks ago.

In 2002, the Nevada State Athletic Commission instituted steroid testing for championship fights, but said that there would be a six-month period during which, absent aggravating circumstances, a fighter who tested positive for a performance-enhancing drug would be sent an “educational letter” rather than be penalized.

"For Oscar to make his comments. Remember I was De La Hoya's promoter. I know what the history is. When [Thomas] Hauser says "sign the waiver or shut up," Hauser knows exactly what he is alluding to. I'm not going to say much about it but remember I was De La Hoya's promoter. I know when it happened and how many times it happened. If you remember there was a grace period that when they tested fighters for steroids," Arum said.
