A catchweight above 135 is purely for Ryan’s benefit. Ryan clearly has no plans to fight at 135 again, with his last 2 fights being over 135 lbs - if Tank didn’t agree to a catchweight, I highly doubt Ryan would have signed. Not that it matters anyway, this is a non-title fight.
I soured on RG a bit because of how it played out. There was all this **** about how Fortuna was having trouble with his weight and other stuff then all of a sudden he weighs in lighter than Garcia and Garcia announces he is never fighting at 135 again.
I think in Las Vegas, 136 it's required to use 10oz gloves. There would need to be an agreement from both sides if they wanted to use 8oz gloves
