Key dates: Aug. 12, finals will be held in five weight classes Venue: ExCel Exhibition Centre Big story: Cincinnati's Rau'shee Warren (above), the first boxer to participate in three Olympics, is among the favorites in the flyweight division (114 pounds). But first he has to win his preliminary bout, something he failed to do in his first two Games appearances. As a team, the U.S. is trying to bounce back from its worst showing ever, winning just one bronze in Beijing. Top U.S. prospects: Middleweight Terrell Gausha of Cleveland, light heavyweight Marcus Browne of New York and heavyweight Michael Hunter of Las Vegas should all contend for a medal. Others to watch: World champions Lazaro Alvarez (bantamweight) and Julio Cesar de la Cruz (light heavyweight) will be out to help Cuba improve on a dismal performance in Beijing, where it didn't win a gold for the first time since 1988, when Cuba boycotted. The Ukraine may have the strongest team after winning five medals -- four gold -- at last year's world championships. Little-known fact: Olympic boxing could undergo a modernization after these Games with International Boxing Assn. President Wu Ching-Kuo saying more than 50 professionals will compete in 2016 in Brazil. He also wants to do away with computerized scoring in favor of pro-style judging and wants boxers to fight without protective headgear.
