Ryan's promoter, Golden Boy, won't choose Fortuna if they are not seeing advantage to their boxer. Remember, Golden Boy is grooming Garcia so for now, it seems they are cherry picking their opponents. But Fortuna, is not to be considered as weak opponent. If he is well-prepared on this one, he can easily beat Garcia. Both should be in their training grounds to prepare for this fight.
Yes, actually he was their first choice prior to Ryan taking a break. Maybe they really know that Ryan can beat this guy. And now that he is available again and they don't want to risk Ryan fighting a guy name Isaac Cruz for a title eliminator, they go on a safest route for their cash cow. So no matter what Ryan says, he is still under Golden Boy and will be protected.
It adds reputation to any boxer's career if he beats a former champion, and Fortuna happens to be a two-time champion, but of course, Fortuna is not on the caliber of Haney and Gervonta Davis, if Jojo Diaz Jr. can beat him why not Ryan Garcia who is a much better fighter, but of course, there's a possibility of an upset, if upset happen this will make a huge disrupt on Ryan Garcia's career he is better off to be an Instagram king than a boxing champion.
