Croatia could be without two influential players for their Euro 2008 qualifiers against Andorra and England with both Dario Srna and and Ivica Olic struggling with injuries.
Attacking midfielder Srna (pictured), recalled to Slaven Bilic's squad after being expelled for the opening qualifier with Russia after breaking a curfew, is now set to miss Saturday's home game with Andorra after picking up an injury in training.
Croatian state radio has also reported that the muscle rupture could rule the Shakhtar Donetsk star out of Wednesday's crunch game against England in Zagreb.
CSKA Moscow striker Olic is also a doubt for both games after being afflicted by a knee problem.
Bilic has already stated he will call on Parma's uncapped forward Igor Budan if Olic fails to recover in time.
Croatia took one point from their opening Euro 2008 qualifier against Russia and will be hoping to justify their status as potential group winners in the coming week.
