Australian Greco-Roman wrestler Hassene Fkiri has been stripped of a Commonwealth Games silver medal for unsportsmanlike behaviour.

The 36-year-old refused to shake hands with his Indian opponent, Anil Kumar, and made the obscene gesture at officials after losing the 96-kilogram gold medal bout.

The bout ended when Fkiri received a third caution for rule breaches.

Fkiri had appeared frustrated during the bout, at one point attempting to slap and headbutt Kumar.

Australian wrestling team manager Kuldip Bassi said Fkiri's gesture was unfortunate.

"At the end, I think he raised the finger and he made a mistake so we lost the silver medal," he said.

"He is really very upset and really disappointed and he went all the way up to the final and he would have been happy with a silver."

Bassi says there are no avenues for appealing Fkiri's disqualification.

Mahabir Parsad, the coach of the gold medallist, said Fkiri's outbust was out of character for an Australian wrestler.

"All Australians behave very good but he lose his temper, so he did bad," he said.

"My wrestler was better and he frustrated your wrestler ... and [Fkiri] broke the FILA rules," he said.

Fkiri was forced to explain his behaviour at a late meeting with Australian chef de mission Steve Moneghetti and Australian Commonwealth Games Association chief executive Perry Crosswhite.
