Henson moved to the French Riviera from Saracens in February, having played just four matches for the London side.

He featured for just over an hour in Toulon’s 21-9 victory over Toulouse on Saturday, and stated afterwards his desire to force his way into Wales’ World Cup squad.

The 29-year-old has not represented his country since the RBS 6 Nations in 2009 however Welsh assistant coach Rob Howley recently hinted a call-up was ‘very likely’.

But the ban means Henson will miss Toulon’s crucial clash with Perpignan this weekend, and as the side currently lie outside the league’s top six, he may only have one further match to convince Warren Gatland of his fitness before Wales’ summer internationals.

Having been on an 18-month hiatus due to injury and other off-field distractions, Henson had begun to show glimpses of the form that made him a key member of The Dragons’ Grand-Slam winning teams in 2005 and 2008.

Henson had also previously stated he wanted to extend his current short-term deal to a full two-year contract at the Stade Mayol.
