London: England have not picked uncapped pace bowler Jofra Archer in a preliminary 15-man World Cup squad but have named him in one-day squads for games against Pakistan and Ireland.
Barbados-born Archer, 24, qualified to play for England in March after a change in residency rules.
He could still make the World Cup if he impresses in the pre-tournament matches as changes can be made up to 23 May.
England play Ireland on 3 May before a five-match series against Pakistan.
The preliminary World Cup squad is unchanged from the drawn winter one-day series against the West Indies, with Eoin Morgan captaining a side who are number one in the ODI rankings.
