Lancashire’s 19-year-old opener Haseeb Hameed is set to be named in England’s squad for their tour to Bangladesh when it is announced on Friday.
If he plays in the first Test Hameed will become only the second teenager to appear in the longer form of the game for England since 1949.
England play two Tests and three one-day internationals in Bangladesh, beginning on 7 October.
Eoin Morgan and Alex Hales have opted out of the tour over security concerns.
In the absence of one-day captain Morgan, wicketkeeper Jos Buttler will lead the limited-overs side.
By choosing not to travel, Hales has given up his place in the Test side, though it is likely he would have been left out anyway after a disappointing home series against Pakistan.
That has opened the door for Hameed, the right-hander who has scored 1,129 runs in the County Championship this season.
His selection will be the latest attempt to solve the longest running problem in the England Test side, with eight different opening partners tried alongside captain Alastair Cook since Andrew Strauss retired in 2012.
Earlier in September, England coach Trevor Bayliss said: “If a player’s good enough, he’s old enough. I wouldn’t have any problem picking him.”
All-rounder Ben Hollioake, who was 19 when he played against Australia in 1997, is the only other teenager to appear in a Test for England since 18-year-old Brian Close made his debut in 1949.
In addition to the vacancy at the top of the order, England will probably need two further batting call-ups, with James Vince likely to be left out and a reserve required.
Northamptonshire batsman Ben Duckett, who has been prolific in domestic cricket and scored 163 not out in a one-day game for England Lions against Pakistan A in July, could be named in both Test and ODI squads.
The tourists will also need further spin options to supplement Moeen Ali and Adil Rashid, with Hampshire left-armer Liam Dawson, 38-year-old Surrey off-spinner Gareth Batty and Somerset slow left-armer Jack Leach possible candidates.
Though there is little more than a week between the end of the second Test in Bangladesh and the beginning of a five-Test series in India, England will only name the party for Bangladesh when the squad is announced at 10:00 BST on Friday.
