I've watched a live stream interview between Casimero and Donaire and it seems the two fighters are still entertaining to have a match on the interview Casimero wants Donaire to send the contract to him and he will read and if he will sign it if he approves of the contract, there's uncertainty on the Inoue Casimero match there are negotiations but nothing concrete has come out yet because Casimero still entertain and is very open to fight Donaire, unfortunately just this day WBC ordered Donaire to take on Graballo as his mandatory challenger.
Donaire have to follow that order from WBC or else, he'll lose his belt so technically no more Casimero and Donaire this year hopefully it'll come next after the fight between Inoue and Casimero, this fight are more possible to happen. Trash talking is very effective with Casimero, I just hope that he is being managed very well so he can still have his reputation and I know, this is all part of the game to market the boxer.
