On December 31, 2005 Ricardo Arona fought Wanderlei Silva for a second time, this time for the Middleweight Championship. Arona threatened to execute the same gameplan, but Silva countered it with a strong takedown defense and an opportunistic striking, including standing away from Arona's guard and kicking his legs. Arona got a decisive takedown at the second round and performed ground and pound, only for Silva to reverse and get free, which forced Ricardo to pull guard. At the final round, Arona managed to take Wanderlei to the ground and attack from top position, with Silva reversing him again and kicking at his legs. Arona lost the match in a discussed split decision.
