England centre Manu Tuilagi is out of the Rugby World Cup after admitting three charges of assault and one of criminal damage.
Tuilagi pleaded guilty to all counts at Leicester Magistrates' Court and was ordered to pay £6,205 in fines after an incident in the early hours of 26 April, which saw the player beat one individual and commit an assault on a police officer.
The 23-year-old has been made unavailable for selection by the Rugby Football Union until January 2016, while his club Leicester Tigers will take internal disciplinary action against him.
"I take full responsibility for my actions and unreservedly apologise to all those involved in the incident, Leicester Tigers and England," Tuilagi said.
"It is something I deeply regret and I totally accept the sentence given by the court. The club and Stuart have been very supportive and I understand their sanctions too.
"I know as an England player the need to conduct myself as a good role model for the game. I am very disappointed because my actions have let so many people down and I can only hope for a future chance to prove myself again."
Currently out with a groin injury, Tuilagi had not played for England since the tour of New Zealand in June 2014 but nevertheless was expected to be included in the World Cup training squad, which is due to be announced on 20 May.
Coach Stuart Lancaster added: "As role models and ambassadors for the game, the highest standards of behaviour are expected from every England player both on and off the field.
"Having spoken to Manu, he understands and accepts both the seriousness of the offences to which he has pleaded guilty and the consequences of his behaviour to his club, country and the game as a whole.
"England will continue to liaise with Leicester Tigers and have every confidence that the club will continue to support Manu in the right way."
