If you didn't yet see it, one of the big stories for today was Floyd Mayweather Sr.'s accusation that Manny Pacquiao uses steroids, a stupid claim that shouldn't have ever come out of his lips, but he's Floyd, so what can you expect?

Pacquiao's trainer Freddie Roach spoke with Fanhouse's Lem Satterfield and shot back with some real venom:

Satterfield: Did you hear that Floyd Sr. implied to the Michigan's Grand Rapids Press -- Floyd Mayweather Jr.'s home newspaper -- that Manny Pacquiao has been on steroids?

Roach: Well [chuckles], we have taken him a couple of times to be tested, and we haven't tested positive yet. I think he's wrong, but all Manny's on is white rice.

Satterfield: Why do you believe that Floyd Sr. would say something like that?

Roach: Steroids? Where in the hell did that come from? You know, these guys, they had to come up with a reason why they lost. They lost because [Floyd Sr.] sucks as a trainer and I had the better fighter.

It isn't the first back-and-forth of 2009 between Roach and Mayweather, of course. The two were on opposite sides of the ring for Hatton-Pacquiao and had a pretty good sniping session just before that fight, which Roach's man won with ease.
