I just read about this over at the scene. I didn't even know about this. Apparently both fighters have agreed to undergo random blood and urine testing leading up to the fight. I guess neither guy wants to leave anything to chance. There will be no conspricy theories about hat men or rogue referees, or drugged up opponents. Hopefully this fight is as good as the last one.
Interesting. I mean, it's all for show as if you're going to dope on a fight of this magnitude the you'd just take substances which can't be detected in the tests, but I suppose it's a good PR excercise.
Those type of drugs just don't grow on trees. That's a real roll of the dice considering you don't know when you're getting tested, and you don't know if your drugs are actually undetectable.
