A hamstring injury will prevent striker Mario Mandzukic from playing in Croatia's Euro 2016 qualifiers against Bulgaria and Malta.

Croatia host Bulgaria on Saturday and then travel to Malta for their final Group H match on Tuesday, but they will have to do so without their first-choice striker.

"Unfortunately, Mandzukic cannot play due to a hamstring injury," Croatia national team doctor Boris Nemec told the Croatian federation's website.

"He has been examined on Wednesday and concluded that he will not feature in these matches."
