Pacquiao, Mayweather reps change stance but fight is not closer - ESPN

Here's an excerpt of the article.

We are OK to move off USADA," Golden Boy Promotions CEO Richard Schaefer, who is representing Mayweather, told ESPN.com. "What we're saying, and what is important to us, is four things -- that the tests be random, that they include blood and urine and the time frame, meaning when do you stop the tests before the fight but know they will still be effective. Three of them we have agreed on -- random, blood and urine. So now it is a matter of the two sides working out the specifics of the cutoff date to assure it will still be effective."
