The test was added as a precautionary measure after he reported suffering a sore throat and a temperature. French media outlets, including L’Equipe, reported that Mbappe was tested for the virus after he missed training for two days.
Mbappe, who has scored 30 goals in 32 appearances in all competitions this term, will be assessed ahead of the visit of Dortmund on Wednesday, Thomas Tuchel said.
“Kylian is sick. He was sick yesterday and he is sick today… and we are trying to maybe have a light practice [with him] this evening. But he did not practice with us the last two days,” Tuchel said.
“We must wait and decide tomorrow morning [whether he will play]. Thiago (Silva) has taken part in all the practices and we can decide tomorrow if he plays or not.
“At this time, I think he is in the team. All the other players are present. Ander Herrera is still injured, but all the other players are present.”
Two Erling Haaland goals either side of Neymar’s 75th-minute strike at Signal Iduna Park on February 18 leaves the score at 2-1 to Dortmund going into the second leg.
Dortmund have won their last three matches since the first leg three weeks ago, and Tuchel revealed his side will look to play offensively at the Parc des Princes, as the current Ligue 1 leaders look to claw their way back into the tie.
