As an amateur, Rau’shee Warren made history by becoming the first American boxer in over 30 years to compete in back-to-back Olympics, competing at the 2004 Olympics in Athens (where he was the youngest Olympic competitor) and the 2008 Olympics in Beijing. In addition, Warren won a gold medal at the 2007 World Amateur Boxing Championships in Chicago, while also winning bronze medals in 2005 and 2011.
Warren made his professional boxing debut on Nov. 9, 2012. Going unbeaten in 14 bouts, he challenged Juan Carlos Payano for the WBA Super and then-vacant IBO bantamweight titles on Aug. 2, 2015, but lost via split decision. Warren challenged for both titles again in June 2016, and that time was successful in winning the belts. However, he’d lose both in his first title defense to Zhanat Zhakiyanov in February 2017.
