Zenit St. Petersburg have been fined €7,400 by the Russian Football Union after a fan offered Anzhi Makhachkala defender Roberto Carlos a banana.
The incident happened just before Zenit's 2-0 win last month when a fan in the stand at the club's Petrovsky stadium was pictured offering the Brazilian great a banana.
After the issue was first raised, Zenit said they were investigating the matter fully with police and subsequently claimed they had banned the fan for life.
However, the Russian Football Union fined the club for the incident having happened in the first place.
Roberto Carlos, who played in three World Cups for Brazil, including the triumphant 2002 campaign, joined Anzhi from Corinthians earlier this year.
Zenit take on CSKA Moscow in the Russian Premier League on Sunday. Luciano Spalletti's men, the current champions of Russia, head the league table with seven points after three games.
