Theo Hernandez has tested positive for COVID-19 on his return from international duty with France, AC Milan said on Wednesday.
The left-back started both of France's games at the UEFA Nations League Finals in Italy, providing a goal and an assist as the world champions defeated Belgium and Spain to lift the trophy.
"Hernandez has tested positive for a swab carried out at home. The relevant local health authorities have been informed and the player is doing well," read a note on Milan's website.
Hernandez is the second member of the French squad to contract the virus in the last week, after Juventus midfielder Adrien Rabiot missed the final following a positive test on Saturday.
Hernandez has been a key player for Milan this season, making nine appearances in all competitions, and the news comes as blow ahead of a busy run of games for the team.
Stefano Pioli's side, who are second in Serie A, face Hellas Verona and Bologna over the next two weekends, either side of a Champions League trip to Porto.
