Cristiano Ronaldo has tested positive for COVID-19 and has left the Portugal squad to isolate.
Italy’s new quarantine rules require at least a 10-day isolation period.
Ronaldo played in the 0-0 draw at France in the Nations League on Sunday, and also in the 0-0 draw against Spain in a friendly last week.
Ronaldo was dropped from the country’s Nations League match against Sweden on Wednesday.
The federation said Ronaldo’s result prompted another round of tests for the rest of the Portugal squad. It said everyone else in the team tested negative.
