Casimero and his camp should just accept their fate that their preparations to have a fight is now gone, they knew that they are already been watched since he got in UK because of his sudden weight loss and the sad thing is they still bend the rules into their benefit even if they knew it's unfair to the opposing party. Casimero's weight problem wouldn't be a problem if he moved up but instead he remained in this division trying to force himself sink his weight even if he cannot do it.
I believe Casimero's camp thinks that if he moves up his power won't be a big thing in that category so they decided to stay in his present weight category to take advantage but it backed fire. I hope I am wrong but I think he will be just another ordinary boxer if he moves up.
But there's no more left for him in his current division, he has violated the rules and has lose the opportunity to defend his title against Butler. He should move up in weight if he feels uncomfortable anymore, looks like we have a new man under Sultan in the Bamtamweight division, not sure if he would stay though after beating Butler.
