Manchester City’s Foden, 20, made his England debut from the start in Saturday’s 1-0 win over Iceland while Manchester United’s 18-year-old forward Greenwood also made his Three Lions bow in the same game as a substitute.
Greenwood and Foden, who shared the same hotel room in Iceland, allegedly brought girls into the room, breaking covid-19 protocols in the process.
A snapchat video obtained and published by Icelandic media outlet DV, showed two girls in the company of the England players in their hotel room.
The two players did not take part in training on Monday morning and England manager Gareth Southgate confirmed later in his press conference that they have been sent home from team camp.
"Unfortunately this morning it was brought to my attention that two boys have broken the Covid guidelines in terms of our secure bubble and so we had to decide very quickly that they couldn’t have any interaction with the team," he told reporters.
"These are two boys I don’t know particularly well at the moment so can’t speak in great depth. I have got to try and speak with them later in the appropriate way. They have got responsibilities and they have apologised.
"We are very clear that no other members of our party have been in contact with the two players - couldn’t join us for breakfast or training. It is a very serious situation and we have treated it that way.
"I think at the moment I’m trying to take a lot of information in. Obviously they have been naive, we have dealt with it appropriately. I recognise their age but the whole world is dealing with this pandemic."
