UEFA is looking into reports that a banana was thrown by Croatia fans toward the pitch during a European Championship match against Italy.
UEFA says it is seeking more information about the incident, which reportedly happened Thursday in Poznan, Poland.
European football's ruling body says it has not opened a disciplinary case against the Croatia football association.
UEFA is currently investigating claims by a Spanish fans' group that some Spain followers made monkey chants at Italy forward Mario Balotelli, who is black, during a Group C match last Sunday in Gdansk.
Balotelli started for Italy against Croatia, and was replaced in the second half.
