Gymnast Panaporn Kosol and field hockey player Surathep Wisawathiron tested positive for steroids in the run-up to the Games in Nakhon Ratchasima and have been handed two-year bans, Chattraporn Nanakorn, head of the SEA Games Doping Control Committee, told Reuters.

"They failed the tests before the Games and are therefore not allowed to compete," Chattraporn said.

"The Sports Authority of Thailand had decided to ban them for two years from the date of the tests."
