Miyagi isn't a great fighter by any stretch of the imagination but he clearly has more experience than Koshikawa and also has a winning record, a record he would like to extend when he returns to the ring.
Although he has been out of action since March 2013 Miyagi is a generally decent opponent and has only been stopped once in 12 bouts with that stoppage coming to current Japanese Light Welterweight champion Hiroki Okada.
This bout will be scheduled for 6 rounds and we would imagine Koshikawa, a very promising 23 year old from Chiba prefecture, will be too good for Miyagi and make the contest appear like a mismatch.
We'll admit we are excited about Koshikawa who made an impressive debut back in March and hope that he can be fast tracked through the domestic rankings and into a title fight of some type in the next 24 months or so. To do that however he will have to make light work of opponents like Miyagi who really should be put away by fighters with title aspirations. Saying that however Miyagi will be determined to get his career back on track and will not roll over for the touted prospect and should be good enough to make things interesting, at least for a round or two.
