Croatia could face punishment by UEFA after a swastika pattern could be seen on the pitch during its European Championship qualifying match against Italy, which ended 1-1 on Friday.
It was unclear whether the symbol was mowed into the pitch or painted on the grass, but it was clearly marked in the middle of the half Italy was attacking in the first period.
Grounds crew attempted to cover it up during halftime, but to little avail.
The match was being played behind closed doors as punishment for racist chanting and other misconduct by Croatia fans during last month's qualifier against Norway.
