Undefeated American boxer Floyd Mayweather Jr. saw nothing wrong with him taking an IV solution prior to his May fight versus Manny Pacquiao.

An SB Nation report earlier revealed that Mayweather was given an IV drip prior to his fight with the Filipino boxer and that the move was approved by the US Anti-Doping Agency (Usada).

It mentioned that Usada informed the Nevada State Athletic Commission (NSAC) that the IV was given to address dehydration concerns and that it was composed of two mixes.

"The first was a mixture of 250 milliliters of saline and multi-vitamins. The second was a 500-milliliter mixture of saline and Vitamin C," added SB Nation.

To defend himself, Mayweather explained in a Boxing Junkie report that he is a clean athlete.

"I follow and have always followed the rules of Nevada and Usada, the gold standard of drug testing. Let's not forget that I was the one six years ago who insisted on elevating the level of drug testing for all my fights," he added.

The boxing star noted his initiative pushed for awareness on the need of drug testing for athletes.

"As a result, there is more drug testing and awareness of its importance in the sport of boxing today than ever before. I am very proud to be a clean athlete and will continue to champion the cause," Mayweather explained.

The recent finding also concludes that the American boxer violated World Anti-Doping Agency (Wada) rules though the injected substances were not banned.

"An IV infusion can dilute or mask the presence of another substance that is already in the recipient's system or might be added to it in the near future," highlighted SB Nation.

But in a statement, Usada said Mayweather disclosed the procedure to them prior to it being administered.

The agency also slammed the report on the discovery of the IV solution saying it was "riddled with significant inaccuracies and misrepresentations based on unsubstantiated rumors as well as anonymous or self-interested sources that have recklessly called our integrity into question."

"It is simply absurd to suggest that we would ever compromise our integrity for any sport or athlete," Usada added.

It was also clarified that Mayweather was granted with a Therapeutic Use Exemption (TUE) by Usada for the IV infusion.

"Mr. Mayweather's use of the IV was not prohibited under the NSAC rules at that time and would not be a violation of the NSAC rules today," the statement furthered.

Asked for his reaction on the matter, Pacquiao told members of the Philippine media in a text message that he feels vindicated with the recent finding.

"Truth finally came out and I was vindicated. Mayweather camp used to accuse me of using PED. Now, look at what happened. I hope Floyd Mayweather would learn a good lesson out of it," Pacman said.

Would this lead to a rematch between the two fighters? Fans would have to wait and see.
