England head coach Stuart Lancaster is unlikely to impose alcohol bans or curfews on the squad ahead of the Rugby World Cup.

Leicester centre Manu Tuilagi will not be considered by Lancaster until January 2016 after being fined for two counts of assaulting a police officer, assault by beating and causing criminal damage. Sale fly-half Danny Cipriani was arrested on suspicion of drink-driving earlier this month and must wait until early August to discover the outcome of a police investigation.

Both incidents took place in the early hours of the morning. Northampton hooker Dylan Hartley, meanwhile, was banned for four weeks for headbutting Saracens hooker Jamie George and was omitted. The squad gathered on Monday when Lancaster addressed them ahead of a potentially momentous home World Cup, which begins at Twickenham against Fiji on September 18.

"The players know their responsibilities and the consequence of poor behaviour and poor decisions," Lancaster said. "I will be very disappointed if we have to deal with any more of these things.

"But we haven't talked about any specific ban in any shape or form."

For the time being Cipriani remains part of Lancaster's initial 50-man squad for the tournament, which will be cut to 31. "He rang me at the time to explain what had happened, that he had been involved in an accident and taken to the police station and released without charge," Lancaster added.

"He said he is due to go back and I said let's wait and see what happens at that point. Players do have accidents in cars. There is nothing more to say until I know if there is anything he has done wrong in the eyes of the law.

"He had had a great game for the Barbarians and was on his way to get packed to go to the airport and this incident occurred. He was concerned as his first port of call was to ring me."

The uncertainty over Cipriani is of little concern to Lancaster. "It'd be a bigger headache if the decision was in early September, but we'll know early August," he said. "The first real decision on selection will not come until the week before the first France game (on August 15 at Twickenham)."
