First, the Arona/Rampage Jackson fight from 2004, which went down at PRIDE – Critical Countdown and was cloaked in controversy. At the 1:10 mark, Arona lands a kick and several shots to Rampage’s melon that seems to temporarily KO Jackson. After pleading with the ref to stop the fight before Rampage pulled it together, Arona found himself again on the bottom-side of the grappling match. Exactly a minute later, Rampage power-slams Arona — which included an accidental, yet illegal head-butt — to end the fight.
And here’s Arona’s last fight, which happened at PRIDE 34 around a year ago. In case your memory is as shitty as mine, the handy internet tells us that Arona got KTFO by Sokoudjou at 1:59 of the first round.
