World Boxing Council president Mauricio Sulaiman, who will be in Las Vegas over the weekend for undefeated Floyd Mayweather’s title defense against Andre Berto at the MGM Grand Garden Arena, says - “I’m sure this is something we are going to discuss” - with respect to the ongoing controversy with Mayweather using intravenous vitamin injection before the fight with Manny Pacquiao, which broke World Anti-Doping Agency guidelines, according to SB Nation's Thomas Hauser.

"In early March, USADA presented the Pacquiao camp with a contract that allowed the testing agency to grant a retroactive therapeutic use exemption (TUE) to either fighter in the event that the fighter tested positive for a prohibited drug," Hauser wrote.

Mayweather received the retroactive exemption after the fight.

In an overseas telephone conversation with the New Standard/BoxingScene.com, Sulaiman said he believes - “it would not be appropriate to give an opinion without having the full facts. I would like to have complete understanding of the situation. I think to come out at this time just before the (Berto) fight it might be more negative than positive to find out something.”

Sulaiman said “nobody has contacted the WBC” about this but pointed out that “we conduct after the fight protocol of anti doing testing but the test they are taking (random drug tests) are out of competition.”

The WBC president said “it’s a little complex, not easy” but claimed that  the article of award-winning boxing writer Thomas Hauser “is full of assumptions” indicating he would not comment on the issue “ before we have full knowledge.”

Pacquiao’s adviser, Michael Koncz ,who spoke to us from his ranch in Ohio said he knew the Hauser story was coming out weeks ago but that he hadn’t read the story.

When asked for his thoughts, Koncz replied, “you are putting me in a tight spot because we have to fight in Vegas again you know and I’m not going to cry over spilled milk. I don’t like the circumstances that came about because we did everything the right way. We informed USADA (about wanting to take a pain killing injection because of an aching shoulder prior to the Mayweather fight) but the [Las Vegas] Commission ruled against us.”

Koncz added - “I’m not going to make any accusations but its not hard to put two and two together.”
