The midfielder has been ruled out of Saturday's game against Andorra and will be examined by the team doctor to determine whether he should stay with the squad for Wednesday's Group E encounter. Croatian radio reported that he had suffered "a muscle rupture".

The Shakhtar Donetsk midfielder joins the forwards Ivica Olic and Milan Rapaic on the sidelines and the coach Slaven Bilic was considering calling up the uncapped Parma striker Igor Budan as a replacement.

The 24-year-old Srna is a key player for the newly appointed Bilic. He scored five goals in Croatia's successful World Cup qualifying campaign, including the decisive goals in the two 1-0 wins against main rivals Sweden, and played in all three games in Germany.

Srna, together with Olic and the former Aston Villa forward Bosko Balaban, was last month expelled from the squad after leaving the team camp to go to a nightclub before their first game in the group, a 0-0 draw against Russia, but the trio were recalled for the games against Andorra and England.
