England rugby player Manu Tuilagi, who was fined for wearing an Opro-brand mouthguard at the Rugby World Cup, is now the face of the company.
The 20-year-old star wing has signed a four-year deal to be the new ambassador for the Opro Group, which manufactures the mouthpiece.
The British company is the largest manufacturer of mouthguards in the world.
Tuilagi - and older brother Alesana, who played in the World Cup for the Samoan rugby team - became infamous during the tournament when they were each fined $10,000 for sporting the unapproved shields.
Company sales director Richard Evans has told British media that the firm had been looking for a face for Opro for a while.
