So maybe we can definitely see Ancajas vs Ioka still in 2022 if Jerwin will win his match against Martinez in February.
Ioka is expected to win this fight though, Fununaga might be a game fighter but he is not on the same level as Ioka. And you can clearly see the Ioka has ring rust in this fight because he could have just walk by and knock out Fukunaga. So just imagine if that is Jerwin that he fought, he might get knock out by Ancajas by a left straight, just saying. And now that the ball is on Ancajas court to win his fight so that they fight will Ioka can be realised in the future.
Ancajas will win the fight and will beat Ioka, that's what I believe so I hope this fight will push through this year so we will see an Ancajas vs Ioka fight this year as well. With lots of unpredictable things happening related to the covid-19, we cannot be sure if the given date would be really realize.
