What makes the story interesting to us is that the WBO title has long rumoured to be up for grabs in a rematch between Chinese star Zou Shiming (8-1, 2) [邹市明] and Thailand's Kwanpichit Onesongchaigym (39-1-2, 24) [ขวัญพิชิต 13เหรียญเอ็กซ์เพลส] on November 5th, as part of the Manny Pacquiao Vs Jessie Vargas under-card.
The rematch between Shiming and Kwanpichit, the #1 and #2 ranked Flyweights according to the WBO when the story first of their rematch first emerged, had been rumoured in Thailand several weeks ago though with Estrada holding on to the title the bout had started to look like it could be for the interim title.
Although the bout is yet to be confirmed by either fighter, their teams or the promoter, it has taken a huge step towards happening with Estrada handing the belt back over and has, in some ways, set the Flyweight in to a series of chain reactions.
Not only are the WBO and WBA "super" titles now vacant but the WBC title is expected to follow suit in the coming days with Roman Gonzalez set to officially vacate to continue his run at Super Flyweight. If that happens then it's likely we'll see unbeaten Thai Nawaphon Por Chokchai (35-0, 28) [นวพล นครหลวงโปรโมชั่น] battle Mexican Juan Hernandez (33-2, 24), with talks already said to be under-way to get that bout on before the end of the year.
Whilst things have suddenly heated up at Super Flyweight, with the emergence of Jerwin Ancajas, the reemergence of Luis Concepcion and the move up of both Gonzalez and Estrada, along with Japanese star Naoya Inoue, it seems likely that we're set for some major shake ups at Flyweight with opportunities likely to come flying around over the next 12 months for fighters like Muhammad Waseem, Daigo Higa, Takuya Kogawa, Yodmongkol Vor Saengthep and possibly even Iwan Zoda.
