The match with Ioka is not possible now if Ancajas will lose. I also don't think that stepping up weight will regain his reputation. It's good to move up weight after a winning match instead of losing 2 times in a row and just to avoid Martinez in the future, he will jump on another division.
He needs to win here, but if he losses, there's no other way but to move up in weight, though it will not hype him but IMO, that's the right thing to do for him to be comfortable in maintaining his weight. He will have to start his journey in a new division and hopefully we will continue to support him.
What we are talking are just the possibilities, but it might change if he wins the rematch.
