Thomas Lemar is a doubt for Atletico Madrid's Champions League tie against Manchester United on Wednesday night.
Lemar was missing from Los Rojiblancos' 3-0 victory over Osasuna in La Liga on Saturday.
The Frenchman was unable to face their domestic opponents after coming into close contact with someone who had tested positive for Covid-19.
It is unknown whether he will be available yet for the visit of United to the Wanda Metropolitano.
In his absence, the 26-year-old's teammates performed admirably with Joao Felix, Luis Suarez and Angel Correa all getting themselves on the scoresheet.
Atletico are currently fifth in La Liga, 15 points behind leaders and city rivals, Real Madrid.
Lemar has not had the most fruitful season for his club side, only managing three goals and six assists in 26 appearances.
