Deysel received a red card for the incident in France’s 96-0 win in Marseille last week and later apologised having received online abuse.

An Independent Judicial Committee have decided the tackle met the top end on the scale of seriousness, which is a 12-game suspension, but have also applied the maximum 50% reduction in sentence following his apology and previous good record.

Deysel has indicated he will attend World Rugby’s ‘tackle school’, a coaching intervention programme, to have a further game taken off his suspension.

The first match of his ban is Namibia’s final World Cup Pool A meeting with Uruguay on Wednesday, where Deysel had been left out of the team selection named on Monday by coach Allister Coetzee.

The committee took into account the "degree of recklessness involved in the offending, the vulnerability of the victim player and the significant injury to him" in finding Deysel guilty.

It is rare for a judicial committee to start at the top end of the scale, with Dupont’s injury, and the outcry that followed, perhaps the biggest factor.

The scrumhalf has had surgery and will remain with France’s squad "under medical supervision" at the tournament, though no official timeline has been given on when he is expected to return to play.

A best-case scenario would be the quarter-finals on the weekend of October 14th-15th.
