CROATIA have called Sime Vrsaljko into their Euro 2012 squad to replace injured midfielder Ivo Ilicevic.
Ilicevic has suffered a ruptured calf muscle.
"I am sorry about Ilicevic," coach Slaven Bilic said. "We have lost another important player who is different to most of our team."
Defender Vedran Corluka also has a thigh problem and will go for tests. Bilic said: "It should be OK, he just felt something in his muscle. Based on the prognosis it shouldn't be anything serious."
Croatia, who had already lost forward Ivica Olic for the tournament, start their Group B campaign against Ireland in Poznan on Sunday.
