Southampton midfielder Stuart Armstrong has tested positive for coronavirus.
The Scottish international returned a negative test for COVID-19 on arrival with the national team on Monday (28).
But a supplementary UEFA test returned a positive result this morning (Wednesday) - around 48 hours later.
The 28-year-old is now self-isolating in line with government guidance.
Southampton says it is taking sensible precautions at its training ground Staplewood Campus.
