USA Track & Field's appeal of the men's 4x100-meter relay team's disqualification in Friday's race has been denied, the IAAAF said Saturday.
The U.S. finished the race third but was disqualified because leadoff runner Mike Rodgers was ruled to have passed the baton to Justin Gatlin outside the first exchange zone of the relay, won by Usain Bolt and Jamaica. The disqualification elevated Canada to the bronze, which it will keep. Japan won the silver.
