Welsh international Gavin Henson has been suspended by French club Toulon following a serious breach of discipline.

“Gavin Henson has been suspended for one week for breaching the club’s code of conduct,” Toulon said in a statement, without elaborating.

Henson, who was released from his contract with Saracens last February after two months with the London club, joined Toulon on a short-term deal but is hoping to sign a two-year contract.

Having been out of the game for 18 months due to injury and other off-field distractions, Henson has begun to show glimpses of the form that made him a key member of Wales’s grand-slam winning teams in 2005 and 2008.

He last played an international in March 2009 but said after Saturday’s 21-9 victory over Toulouse that he hoped his performances in France would earn a Wales recall and a possible first World Cup appearance.

He will miss Toulon’s forthcoming match against Perpignan this Saturday.

The flamboyant star had been hoping for an international recall having not played for Wales for over two years following a self-imposed hiatus from rugby.

Earlier this month, Wales assistant coach Rob Howley said it was “very likely” Henson – who can play full-back, centre or fly-half – would feature for his country in June ahead of the start of the Rugby World Cup in New Zealand in September.
