Harlequins’ uncapped forward Alex Dombrandt in line to be named in England’s first World Cup Training squad.
The uncapped flankers selection comes after a strong performance against the Barbarians earlier this month.

Meanwhile, hooker Dylan Hartley, scrum-half Danny Care and flanker Chris Robshaw are understood to be among the high-profile omissions.
Jones then names his final training party, including players from finalists Exeter and Saracens, on 4 July.
