Croatia defender Josip Simunic has been given a 10-game ban by FIFA for singing a "pro-Nazi" song.
The FIFA punishment for discriminatory behaviour means Simunic will miss the World Cup. He was also fined €23,000.
While celebrating on the pitch following Croatia's playoff victory over Iceland last month, the Australian-born defender led Croatia fans in a chant of Za dom ("For the homeland"), a song with Nazi connotations.
The song has been linked to the Croata's fascist movement during World War II.
At the time of the incident, Simunic had denied that he had far-right sympathies and claimed he was demonstrating "love for his Croatian homeland".
The Croatian State Attorney's Office fined him approximately €3,000 for the incident.
Simunic was at the centre of controversy at the 2006 World Cup - although that time he was not at fault. He was the Croatia player who was shown three yellow cards before being sent off by referee Graham Poll in a group match against Australia.
