England centre Manu Tuilagi has been fined $NZ10,000 for wearing a mouthguard showing a sponsor's logo - a week after his brother Alesana was fined for the same offence.
An England spokesperson said Manu Tuilagi has been fined by the International Rugby Board for the "genuine error" of wearing the mouthguard during the match against Georgia in Dunedin on 18 September.
The 20-year-old powerhouse said he and older brother Alesana, who plays for Samoa, wore the same brand, Reuters reports.
Fans annoyed at what they considered the harsh penalty for Alesana raised thousands of dollars towards his fine with a televised "sausage sizzle" in Auckland.
World Cup organisers have declined to release details of fines issued to other unions for various offences, saying it was up to the individual countries to announce details if they chose.
