Just bloodtest, handtest, and do everytest available on Margarito before and after his fights, then he can prove he is clean.
All I can say is that the incident was an unfortunate part of Margarito's prof boxing career. Had there been no issue on the pads he would be probably fighting the likes of Manny Pacquio or somebody who has a big name at 147. Whoever wrapped the pads did not do his job properly. Interesting note about Margarito's career is that he beat Cotto, Cotto beat Mosley, Mosley beat Margarito.. Funny thing is that Floyd FANS are shouting with joy that Floyd beat Mosley they forgot that Cotto already beat Mosley much earlier when Mosley was still younger:!:
