Boxer Ryan Garcia denied using performance-enhancing drugs in a video posted on social media Wednesday night after ESPN reported that he had tested positive for a banned substance. Garcia defeated Devin Haney, a former amateur rival, by majority decision on April 20 in New York. Garcia knocked Haney down three times and handed the WBC super lightweight champion his first loss but did not win the title because he was over the weight limit. ESPN reported that the 25-year-old Garcia tested positive for the performance-enhancing substance Ostarine the day before and the day of the fight, citing a Voluntary Anti-Doping Association letter.
