Worapoj Petchkoom, a popular Thai boxer and the national team flag holder at the Beijing Olympics, may miss out on the medals in London, after appearing in his underwear in a photoshoot for gay magazine, Stage.

Officials from the Amateur Boxing Association of Thailand (ABAT) have warned Petchkoom that he may serve a one year ban from boxing, after concerns were raised that his actions were inappropriate.

General Thaweep Jantharoj, the President of the ABAT, said: "We will question him. After we listen to him, we will mete out punishment," reports Inside the Games.

Petchkoom claims that he did not realise that he was posing for a gay magazine and denies being homosexual.

Petchkoom, 28, told the Joh Jai TV programme: "I thought it was an honour to be invited to grace the cover of a magazine on its third anniversary.

"I became sceptical when I was told to wear just underpants.

"They said everything was going to be okay because it would show my abdomen muscles."
