"England will continue to liaise with Leicester Tigers and have every confidence that the club will continue to support Manu in the right way."
Samoa-born Tuilagi pleaded guilty to one count of assault by beating, one count of criminal damage and two counts of assaulting a police officer.
The incident took place in the city of Leicester during the early hours of April 26. He lashed out at a taxi driver, grabbing him by the throat before kicking the cab's wing mirror.
Two female police officers tried to put handcuffs on him and pushed the pair of them hard in the chest.
"I know as an England player the need to conduct myself as a good role model for the game," said Tuilagi.
"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."
Tuilagi has been sidelined since October with a groin injury but was expected to be fit enough to be considered for selection in England's squad for the Rugby World Cup, which starts in September.
He has not played for England since a 36-13 loss to New Zealand in Hamilton in June 2014.
