Experienced Wolfsburg striker Ivica Olic is in doubt for Croatia s Euro 2012 campaign due to a thigh injury.
Olic, 32, picked up the problem during his team s 1-1 friendly draw against Norway on Sunday, and may not regain fitness in time for the tournament.
Croatia coach Slaven Bilic may now be forced to reconsider his attacking options ahead of their Euro 2012 opener against Republic of Ireland on June 10.
I cannot guarantee that Olic will play at the Euros, Croatia squad doctor Zoran Bahtijarevic told Sportske Novosti.
We did the first medical exam at the stadium in Oslo to check the flexibility of the muscle. It seemed fine, but he will undergo a complete scan on Monday in Munich.
I m an optimist. So far the medical evidence suggests he could (play at the Euros), but let s wait until the scan.
Following the Group C match against Republic of Ireland, Croatia take on Italy and then tournament holders Spain.
Olic has agreed a switch to Wolfsburg on a free transfer from Bayern Munich, bringing an end to his three-year stay at the Allianz Arena.
