An under-19 friendly between England and Scotland on Thursday was abandoned during the first half after the visitors' head coach Billy Stark tested positive for Covid-19.
Hosts England led 3-1 in the game at St George's Park when it was halted.
The Scottish FA said Stark tested negative when the squad met up, but a second round took place on Thursday before a scheduled re-match on Sunday.
He will now "travel home in isolation and will self-isolate for 10 days".
"The playing group and the rest of the backroom team will undertake precautionary self-isolation for 14 days, whilst the Scottish government undertakes a formal risk assessment to assess who Stark was in close contact with during the camp," a Scottish FA statement said.
Scotland Under-19s second game against England on Sunday has now been postponed along with the scheduled Under-17s match at St. George's Park on Saturday.
