Tapales was originally scheduled to fight Mexican Noe Martinez Raygoza (16-5, 5) though unfortunately Raygoza pulled out with less than a week to the fight. Thankfully the show's promoter managed to get Tapales an opponent on short notice, though it's not a great one with Galih Susanto (6-3, 1) being the late fill in.
Susanto, from Indonesia, is a relatively unknown fighter, though he did manage to go the 12 round distance with Thailand's Denkaosan Kaovichit last year in a PABA title fight. The big problem for Susanto however will be that he's got this fight with next to no preparation time and that he'll also be needing to move up a division from Super Flyweight.
Tapales, pictured, is ranked #10 by the WBO and will know that his ranking is on the line, though will also be aware that Susanto is 0-2 outside of his native Indonesia and has hardly won a round in his two fights on the round.
