Cintron leaps out of the ring sometime in the 3rd round, assuming he manages to stay on his feet and conscious for that long.
Cintron is and always has been shit Cuevas wood hook with passion and force him to brawl... CIntron, being the feather-soft fighter he is, would be easily discouraged and eventually stopped
Cuevas somewhere in the middle rounds, perhaps a bit sooner. Kermit would put up a fight for however long his heart will allow, which wouldn't be very long.
