You see there is some contradiction here. Pacman camp have refused to sample his blood 30 days before the fight but then said in the interview Pacman doesn't want his blood drawn at the weigh in or at the conference because it will unsettle him...so which one is it? Before it was refusing to take a blood test so early, other excuse is refusing to take one so close to the contest.
At the same time I don't see why such bespoke and special conditions for blood testing have been outlined by Team Mayweather unless they think that the Pacman has something to hide and are trying to exploit it. I'd let the boxing do the talking personally.
