Samoa's Eliota Fuimaono-Sapolu will not be sanctioned for his angry Twitter attack on the International Rugby Board.

Fuimaono-Sapolu accused the IRB of unfair treatment following his team's 17-10 defeat by Wales on Sunday.

Samoa were afforded just four days between Rugby World Cup matches, while Wales enjoyed a week to recover from their previous outing.

Fuimaono-Sapolu called the IRB 'unjust' and compared the situation to 'slavery, the holocaust and apartheid'.

The Gloucester centre could have been disciplined for breaching the RWC Code of Conduct, which includes specific guidelines on the use of social media.

But following a meeting between IRB officials and the Samoa camp in Auckland on Tuesday, Fuimaono-Sapolu has escaped punishment.

"Rugby World Cup Limited officials met with the Samoa team management today to discuss comments made by a member of the Samoa squad via the public social media network Twitter," tournament organisers said in a statement.

"While RWCL believes the nature of the comments to be inappropriate and has warned the Samoa Rugby Union regarding future social media conduct, RWCL has accepted an official apology and is satisfied with the proactive measures that the Union has outlined to RWCL to address the matter."

"There will be no further action, and RWCL considers the matter to be closed."

In the original tweets, Fuimaono-Sapolu wrote: "IRB, Stop exploiting my people."

"Please, all we ask is fairness. If they get a week, give us a week. Simple. £equity £justice."

He later added: "Ok, it's obvious the IRB are unjust. Wales get 7 days, we get 3. Unfair treatment, like slavery, like the holocaust, like apartheid. F... U. Give Wales 3 days off, and give Samoa a week!! We would kill them!!!"

The fixture schedule has been devised to ensure matches involving top-tier nations would be broadcast during prime-time slots to maximise commercial revenue.

According to the IRB, revenue from the tournament will be reinvested in high-performance centres in countries such as Samoa.

The governing body claims the alternative would be to reduce the tournament size, restricting the chances of developing nations to compete.
