Croatia forward Ivica Olic has been ruled out of the European Championships after scans revealed his thigh injury was worse than first feared.

After picking up the knock in Saturday's 1-1 draw with Norway, the 32-year-old Bayern Munich man underwent a scan today and has been declared unfit for the next four to six weeks.

A statement on the Croatian Football Federation's official website said: "Unfortunately, Ivica Olic will not participate at the European Championships in Ukraine and Poland, and as his replacement, coach Slaven Bilic has called Nikola Kalinic."
