Goalkeeper Thibaut Courtois will miss Real Madrid's match at Lille in the Champions League on Wednesday because of a muscle injury.

Following tests on Monday, Courtois was diagnosed with an abductor injury in his left leg, Madrid said.

Courtois was hurt in the 1-1 draw at Atletico Madrid in the Spanish league derby on Sunday. He played the entire match at Metropolitano Stadium.

Madrid began the defense of its Champions League title by beating Stuttgart 3-1 at home.

Included in Madrid's squad was Kylian Mbappé, who missed the derby against Atletico because of a hamstring injury.
