The weights are in. Retired four-time world champion Acelino "Popo" Freitas, and undefeated World Boxing Council South American middleweight champion Michael "The Brazilian Rocky" Oliveira will clash at Conrad Punta Del Este and Resort Casino in Uruguay. The 10-round Freitas-Oliveira main event will be contested at 154-pounds. Freitas weighed in at 154.8-pounds, while Oliveira was 152.9.

The 36-year-old Freitas (38-2, 32 KOs) is a state legislature in Brazil, where he is a national sports hero and revered in a country preparing to host the next World Cup and 2016 Summer Olympics. 'Popo' has been retired for nearly five years, since his last fight April 28, 2007, but he will come out retirement to take on the popular 21-year-old Oliveira (17-0, 12 KOs), rated No. 14 by the World Boxing Council ("WBC"), has fought three times in his native Brazil in an effort to establish himself as Freitas' successor in Brazilian boxing circles. Born in Sao Paulo, he moved to Miami when he was only two weeks old, and now finds himself training to fight his country's second-greatest boxer, Freitas, to only Hall of Famer Eder Jofre.
