ICC World XI team will consist of two players from Pakistan and New Zealand. This match will also see Afridi make a return to worldwide cricket on a one-off basis having last played for Pakistan in the World T20 in 2016.
Billings, a 26-year-old wicketkeeper-batsman, has 30 caps for England in ODIs and T20Is, and has just returned from a stint in the IPL playing for the Chennai Super Kings.
Eoin Morgan's finger injury means former Pakistan captain will lead the World XI side in their upcoming match against the West Indies - a T20 worldwide for the #CricketRelief initiative, the official ICC website said on Wednesday.
Morgan has been replaced as captain by veteran dashing Pakistani all-rounder Shahid Afridi while Englishman Sam Billings takes his place in the squad.
Eoin Morgan was initially named as the captain of the side, but the left-handed batsman has pulled out following a fractured finger.
England bowler Tymal Mills and Surrey all-rounder Sam Curran have also been added to the World XI squad. Though he was in and out of the side during the competition, his 23-ball 56 helped the side, who finished as champions, earn their first win in this year's tournament.
Tom Curran - the man who replaced Plunkett - retains his place, with Craig Overton missing out.
England's limited-overs captain Eoin Morgan has been included in the one-day worldwide (ODI) squad to face Australia and Scotland despite suffering a finger injury, the England and Wales Cricket Board said on Wednesday.
The exhibition match is scheduled on May 31 at Lord's, to raise funds for the damages incurred due to the Carribean islands.
An x-ray following a bruised finger from a fielding mishap during a domestic match for Middlesex revealed the fracture in his finger and sidelined Morgan. "It is not a huge concern, it is one we can hopefully manage past in about a week", said Flower, according to official International Cricket Council (ICC) website.
