England team officials said Tuesday that Tuilagi broke the sponsorship and ambush marketing rules of the International Rugby Board in England’s 41-10 win over Georgia on Sept. 18 in Dunedin.

Tuilagi says “I wore the wrong gumshield” and “it’s been dealt with.”

His older brother Alesana Tuilagi was also fined NZ$10,000 ($7,500) after the Samoa winger wore the same branded mouthguard as Manu in his team’s 27-7 victory over Fiji on Sept. 25 in Auckland.

England plays France in the quarterfinals at Eden Park on Saturday.
