Luka Modric played a full 90 minutes in Croatia's 3-1 loss to Brazil on Thursday, but he suffered a foot injury in the match. Modric's status for Wednesday's match against Cameroon is uncertain.

“Luka is in Salvador and our doctors are with him in the hospital," said Niko Kovac.

“He has to go though some exams and then we will see how serious it is.

“God forbid that something serious happens to him. That would be a huge blow for us.”
