Luka Modric will be out for three months with a torn tendon in his thigh.
Modric picked up the injury in a Euro 2016 qualifier against Italy on Sunday.
"The Croatian national team and Real Madrid midfielder will be away from the football pitch for about three months after the injury sustained in the encounter between Italy and Croatia," said a statement on the HNS website.
Modric has been a critical part of Real Madrid's midfield again this season.
