And he made the right decision because the belt of Casimero wasn't stripped anyway, and if he fought the replacement, he still has to fight Casimero again for the championship fight, it's gonna be a double effort on Butler and there's no assurance that he would win against the replacement.
Smart move by him, and the organization for not stripping the belt from the champion.
I would say that it is a good decision by the WBO of not stripping Casimero the belt because Casimero is a bigger name than Butler and the could generate money if ever there is a unification bout between Casimero and Inoue/Donaire as the hype is already there.
This time it is the turn of Casimero to put on the work and be at weight during fight time, hope the rumors of him not getting the weight is just fake news.
Speaking of that organizations decision then of course they would really be always minding about revenue and they couldnt really just make out those opportunities do pass by.
thats why these kind of decisions would or should be followed but this one isnt really that obvious though but somewhat this make things more interesting.
