why isin't cotto/margarito a unify fight?

[BALLISTIC]

margarito does hold the IBF or is it a unify fight? makes no sense..

[KingTito]

I believe Margarito had to give up his belt in order to take this fight, but I could be wrong.

you are right

[KLITSCHKO.]

Margarito dropped the belt so he could fight Cotto

Judah and Clottey will be fighting for the vacant IBF Title

[Ray*]

Both clottey and Judah are fighting for the IBF belt.

why would he have to give it up..wtf he beat cintron for it.....****** shiet the fact thats its a unify fight, it would be more intense..
