Croatia's key midfielder Luka Modric injured in World Cup loss against Brazil

Playmaker Luka Modric is a doubt for Croatia's next World Cup match against Cameroon after picking up a foot injury in his side's loss to Brazil in the tournament opener.

Croatia team officials said Friday that Modric was taken to a hospital in Salvador, near the squad's training base, to check the extent of his injury after feeling pain.

Modric's absence in the June 18 match against Cameroon would be a major blow for Croatia which lost 3-1 to Brazil on Thursday and is bottom of Group A together with Cameroon, which lost 1-0 against Mexico on Friday.

The skillful Real Madrid midfielder is the backbone of the powerful Croatian midfield.
