I was basing on the OP as it stated it will happen in June 15..
Sorry my bad, i thought that this fight is an undercard for that cruiserweight final but as i reviewed the article, this fight has not been scheduled yet but definitely will face each other though.
I'm going to update OP later, sorry for the inconvenience that i may have brought to everybody here.
I did ask about the listing of this fight in sportbetting.io, they said they final date so the reason why they didn't list it. I got excited to see the odds of the fight but the previous post about the odds may not be true. I have been watching the youtube highlights of both fighter and i can see inoue has a chance to win but definitely not that big. He fights with just amateur fighters unlike Donaire.
