Originally Higa's opponent was announced as Jayar Estremos (11-12, 4), in a bout that seems to have been very much underwhelming. Since then it's been reported that Estremos is out, and he has been replaced by fellow Filipino Diomel Diocos (10-1-3, 3), in what looks like a much better bout on paper.
The once beaten Diocos will, like Estremos, be considered an under-dog against Higa but should be a more interesting test than Estremos would be. In fact it would be a bout that sees Higa up against someone who has never been stopped and will have a point to prove coming in to this contest.
The 23 year old Filipino hasn't fought anyone of any note but has only lost once, more than 3 years ago, with that loss being a razor thing decision loss to Fel Morales.
For those unaware the whole Dynamic Glove card will be aired live on G+ on February 4th and will be well worth tuning into with several really intriguing bouts, including the brilliant main event. It also seems likely that this will be Higa's final bout before a potential world title bout later in the year.
