Gloucester flyhalf Danny Cipriani has been left out of England’s World Cup training squad that will fly to Italy.

Cipriani was originally selected in Eddie Jones’ 35-man training squad earlier this month but spent time away from the team to do specialised strength and conditioning work along with Bath duo Sam Underhill and Anthony Watson.

The 31-year-old Cipriani was named Premiership player of the year and RPA players’ player last season but the last of his 16 England caps came in June 2018 tour of South Africa, where he made his first start for a decade.

Coach Eddie Jones has named a 38-man group for a 12-day heat camp starting in Treviso on Monday to help acclimatise players to conditions expected during the tournament in Japan.

Underhill and Watson will travel with the squad, while uncapped Harlequins centre Joe Marchant joins the group for the first time.

“Treviso is a hard yards camp with conditions similar to Tokyo,” said Jones, who will eventually trim the group to 31 for the tournament in Japan in September and October.

“Team training will be about being adaptable and off the field enjoying each other’s company.

“Selection is absolutely challenging, we have left some good players doing work at their clubs and they must be ready if called up.”

England will play four World Cup warm-up games – home and away to Wales and home against Ireland and Italy – before heading to Japan.
