Croatia midfielder Ivo Ilicevic has been ruled out of the European Championship because of a left calf injury.
Coach Slaven Bilic said Thursday that UEFA has given Croatia permission to replace the Hamburg midfielder with 20-year-old Sime Vrsaljko.
Ilicevic's injury came during training Wednesday and the expectation at the time was that it was only a minor strain. But Bilic says doctors in Warsaw ruled the 25-year-old Ilicevic out of Euro 2012.
Croatia plays its first game in Group C on Sunday against Ireland. Spain and Italy are the other teams in the group.
