Sadly for fans anticipating that bout it appears to be off with Estrada vacating his WBA title rather than following the order of the WBA and defending the crown against the 3-weight Japanese champion.
With Estrada giving up the WBA title he does avoid the mandatory with Ioka however he does retain, for now, the WBO title and will be expected to fulfil their mandatory obligations, when he returns to the ring. Rumours are that he may be set to vacate that title too and make the move up to the very exciting Super Flyweight division, chasing a rematch with newly crowned WBC Super Flyweight champion Roman Gonzalez or a bout with Japanese star Naoya Inoue in 2017.
As Estrada's vacated the WBA title we're now expecting to see Ioka return on New Year's Eve against an opponent of his choice, potentially a big name to end the year. As for the WBO belt if Estrada vacates that as well, as some have suggested, then we may well see the rumoured rematch between Zou Shiming (8-1, 2) [邹市明] and Kwanpichit Onesongchaigym (39-1-2, 24) [ขวัญพิชิต 13เหรียญเอ็กซ์เพลส], which has been rumoured for November 5th.
Sadly for Estrada it's another hit to a career that promised so much. Back in 2012 he gave Roman Gonzalez a tough bout before winning the WBA "super" and WBO Flyweight titles with a decision win over Brian Viloria. Wins over Giovani Segura and Hernan Marquez added more names to record but with almost a year of inactivity boxing fans do have a short memory and the Mexican could end up being forgotten sooner rather than later if he doesn't get back into the ring. Whilst he has had injuries, notably to his right hand, this is the sort of decision that could further alienate him from fans, especially given some of his comments on social media, especially in relation to Saul "Canelo" Alvarez.
