### Controversy

The bronze medallist, Joshua Hall from the Philippines, is expected to have his bronze medal upgraded to a silver medal, after the International Swimming Federation (FINA) slapped a two-year ban on Indonesian swimmer Indra Gunawan, who won the silver medal in the event. Gunawan’s urine sample tested positive for Methylhexaneamine, a performance-enhancing substance, during random testing at the 4th Asian Indoor and Martial Arts Games held in July 2013.
