Lionel Messi has tested positive for COVID-19.
The Paris Saint-Germain forward had returned to Argentina, according to multiple reports, with the French Ligue 1 having paused for the winter break.
PSG left-back Juan Bernat, midfielder Nathan Bitumazala and back-up goalkeeper Sergio Rico have all tested positive for the virus as well.
The 34-year-old will not return to Paris until he has returned a negative test, coach Mauricio Pochettino confirmed.
Messi signed at Le Parc des Princes last year on a free transfer, after his contract with Barcelona wound up.
He has experienced an up-and-down start with Les Parisiens, having netted only once in 11 league appearances, while injury has kept him out of five matches.
The Argentinian has sparkled in the UEFA Champions League, however.
His five goals in five appearances helped PSG put a gap on Club Brugge and RB Leipzig in the group stage, and book a meeting with Real Madrid in the knockouts.
Messi was awarded a seventh Ballon d’Or in November, having guided Argentina to the 2021 Copa América.
It was Messi’s first major title for his nation, and La Albiceleste’s first trophy since the 1993 Copa América.
