The controversy surrounding an SB Nation report by Thomas Hauser detailing Floyd Mayweather using an IV just before his May 2 win over Manny Pacquiao to aid in rehydration has his opponent and opposing promoter from that night feeling mixed emotions, as you might expect.

While Mayweather denies all wrongdoing, Pacquiao says he's feeling vindicated:

"Truth finally came out and I was vindicated," Pacquiao texted to PhilStar's Abac Cordero. ... "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," Pacquiao continues.

Pacquiao's promoter, Bob Arum, is a bit more upset about the situation, even if he doesn't see anything changing:

"It is very disturbing," Arum told USA TODAY Sports in a telephone interview. "Yeah, I am outraged. But I don't know what we can do about it. I can't change the result."

Arum also said he's often wondered why Mayweather waits until so close to a fight date to announce his upcoming bouts, in reference to Victor Conte saying that the closer one gets to fight dates to begin testing, the more time a fighter would have for anything illegal to leave their system, while still reaping the benefits.

This is a story that has just completely overshadowed Mayweather's fight on Saturday against Andre Berto, a fight that had very little buzz behind it but now has been drowned out by a potentially far more intriguing story.

How are you feeling about all of this? (Besides "sick of hearing about Mayweather-Pacquiao," I mean.)
