Another one of France’s 2018 World Cup -winning team is injured and was ruled out of the title defense on Wednesday, and likely for the rest of the season.

Lucas Hernandez, the starting left-back four years ago, lasted just eight minutes of France’s opening game against Australia on Tuesday before suffering a ruptured ACL in his right knee.

“We’re losing an important element,” coach Didier Deschamps said in French soccer federation statement. “Lucas is a warrior.”

Hernandez seemed to twist his right knee while his leg was off the ground in the play that saw the cross delivered for Australia to score and take a shock early lead in France’s 4-1 win.

The 26-year-old Bayern Munich defender was clutching at his knee in pain even before landing on the turf.

While his younger brother Theo prepared to come on as a replacement, Hernandez was treated on the pitch for a couple minutes before limping around the field to exit down the players’ tunnel.
