With the inability to weigh in against Saito it appears the Japanese Boxing Commission (JBC) have had enough of Muranaka's issues and today, following a meeting related to the JBC rankings, they announced that they were indefinitely suspending Muranaka.
The JBC have made it clear this year they will not accept fighters missing weight any more. Muranaka is the third fighter, this year, to be given an indefinite suspension, following Daigo Higa [比嘉 大吾] and Luis Nery, who both failed to make weight earlier this year.
Unfortunately for Muranaka, who is best known internationally for losing in a WBA Super Flyweight bout to Kal Yafai, he is now 33 years old. He's not a youngster like Higa and Nery who can take their punishment and come back with most of their career ahead of them. Instead Muranaka's career is possibly now over. He will have to regain the JBC's trust, and hope that they end the suspension sooner rather than later. Sadly however it's likely that the JBC will want to make an example of Muranaka due to the multiple time that he's missed weight already.
