England were fined £10,000 and their fitness coach Dave Reddin was suspended for two matches after being found guilty of misconduct, World Cup officials have announced.
Tournament organisers announced the English RFU had ignored the instructions of touchline official Brett Bowden when they sent winger Dan Luger, a 16th player, on to the pitch as a late replacement during Sunday's pool C game against Samoa.
A complaint against Reddin over an alleged altercation with match official Steve Walsh was dismissed.
