Did Diaz get stripped of his WBO belt, for not facing Katsidas (even though the IBF was MAKING him face Cambell)? According to boxrec, it was only for the IBF title. But I haven't been able to watch the fights tonight, so I wouldn't know.
The belts don't really matter.. Diaz was pretty much the man to beat at that weight. So Campell is the man to beat now.
