For Oliva this is a huge chance to re-announce himself on the world stage after a series of lesser bouts following his August 2011 loss to Ulises Solis, in his only previous fight at world level. Although he'll be the clear under-dog he'll be a fighter fancying his chances at claiming the most notable victory of his career and effectively moving in to a "real" world title bout.
Whilst the bout is a major contest for Oliva it's also a big one for Mthalane. The South African, who was recently stripped of his IBF Flyweight title, will be fighting for the first time since September 2012. Although stripped of the IBF title this will effectively be a world title fight for Mthalane who will, for the first time in a long time, be paid like a world champion.
Prior to being stripped of his IBF title Mthalane was set to be paid "peanuts" to defend against Amnat Ruenroeng. This fight will however net Mthalane over $90,000 (US), a significantly improved figure on what he'd have been paid for fighting Amnat.
For those wondering what has since happened to the IBF title, it was won earlier today by Amnat who managed to out point Oliva's Filipino compatriot Rocky Fuentes in a bout that effectively replaced Amnat's originally scheduled bout with Mthalane.
