Calvert-Lewin on target in dream England debut
An unnamed member of one of the teams' backroom staff reportedly returned a positive test for COVID-19.
The Football Association confirmed the game was halted in the first half "in line with COVID-19 protocol", with the teams then returning to their dressing rooms at St George's Park.
England was leading 3-1 at the time.
The senior England side face Wales in a friendly at Wembley later on Thursday, with Scotland taking on Israel in a Euro 2020 play-off semi-final.
