Originally we had heard that Estrada would be defending the belt on April 19th against unbeaten Filipino Joebert Alvarez (13-0-1, 6) though it appears that plans, somewhere have changed and instead Alvarez will fight this weekend against Julian Rivera (13-8-1, 2), still in Mexico.
Whilst we've not heard the official line about why things aren't as first reported we're assuming that Alvarez's team have realised he's not ready and have decided to let him get more experience before putting him in with a foe as dangerous as Estrada.
For Mepranum this will be his second word title fight after having previously been stopped by Julio Cesar Miranda in a bout for the WBO Flyweight title back in 2010. Since that loss the Filipino has gone 5-1 with his only loss coming to Hernan Marquez.
For Estrada this will be his second successive defence against a Filipino having out pointed Milan Melindo last year in his first defence of the titles.
