France rugby captain Antoine Dupont ruptured cruciate ligaments in his right knee during the win over Ireland in the Six Nations, denying the superstar scrumhalf the chance to potentially lead his team to the title next weekend.

France captain Antoine Dupont suffered a potentially serious knee injury in his team's Six Nations clash against Ireland at the Aviva stadium, an angry coach Fabien Galthie said on Saturday.

No Irish player will appear before the Six Nations disciplinary committee despite France demanding that two do so for the ruck clear-out that caused Antoine Dupont a serious knee injury, the French rugby federation said Monday.
