Well only problem with thinking he did it in Cotto fight is that you have to look at all his fights i mean look at his fights with Clotty and Williams. They were not battered or bruised and i guess if we assume he did it Cotto must of done it to them as well they fights were pretty close together. I still going to wait till they come back with the substance because judging buy Margritos fights with Clotty and Williams he did not seem to bruise them up badly i really like to see how much more effect it has then a fist.
