England head coach Stuart Lancaster is awaiting the outcome of the police investigation following Danny Cipriani's drink-drive arrest before determining whether the fly-half can be included in his World Cup squad.
England began their summer training camp on Monday without centre Manu Tuilagi and hooker Dylan Hartley, who will miss the tournament after Lancaster responded decisively to recent lapses in judgement and Cipriani could join them on the absentee list.
The Sale fly-half was arrested on suspicion of drink driving earlier this month and must wait until early August to discover the outcome of a police investigation.
For the time being he remains part of Lancaster's initial 50-man squad for the World Cup, which will be cut to 31 ahead of the opening match with Fiji at Twickenham on September 18.
Lancaster expects Cipriani to be able to go to the United States for the forthcoming high-altitude training camp in Denver, Colorado.
Wing David Strettle has withdrawn from the England squad to prepare for his move to French Top 14 side Clermont Auvergne after leaving Saracens.
