Switzerland winger, Xherdan Shaqiri, has tested positive for COVID-19, the country’s football federation said on Tuesday.
This is one day after the 28-year-old rejoined the national team for the first time in over a year.
The Liverpool player last appeared for Switzerland in the Nations League finals in June last year.
He arrived at the team hotel on Monday afternoon ahead of a friendly at home to Croatia on Wednesday.
The federation said Shaqiri has now been put in isolation, indicating “We are clarifying how to proceed with the local health authorities.”
Two of Shaqiri’s Liverpool teammates, Sadio Mane and Thiago Alcantara, tested positive in the last week.
This is the latest blow to Shaqiri, who has fallen out of favour at his club.
He featured in only seven Premier League games last season, starting two of them, and his only appearance in the current campaign has been in the Carabao Cup.
Shaqiri who asked to be left out of the Swiss squad one year ago to concentrate on his club football had not been included since until his recall for this month’s games.
Switzerland also visit Spain for a UEFA Nations League match on Saturday and Germany three days later.
