Rostov are likely to face a Uefa disciplinary case for fan racism after a banana was thrown on to the field during the Russian club’s Champions League game against PSV Eindhoven.

The Fare network, which monitors racist incidents for Uefa, said on Thursday the banana was thrown about eight minutes into Wednesday’s 2-2 draw. It remained on the field for at least 15 minutes.

“We have reviewed the media from the match and have seen that it took place in the eighth minute after Rostov scored and took place in the opposite end to the action,” the Fare director, Piara Powar, said in a statement. “A supplementary report to Uefa will follow from us this morning.”

Vyacheslav Koloskov, the Russian Football Union’s honorary president, said the incident could tarnish Russia’s image as it prepares to host the 2018 World Cup. Rostov’s home city of Rostov-on-Don will stage games during the tournament.

“This banana could cost us heavily,” Koloskov said. “It’s not to be tolerated at any time, especially now. Rostov may be forced to play a game behind closed doors.”

Non-white players, including the former Brazil defender Roberto Carlos, have been taunted with bananas during Russian league games in recent years. Champions League games have also seen racist incidents involving Russian fans, with the league champions CSKA Moscow repeatedly punished by Uefa for offences including monkey chants aimed at opposition players.

In 2014, the Rostov coach Igor Gamula was suspended by Russian football authorities for derogatory comments about black players in his team. Following protests by Rostov’s players, he was removed from his post and given a role with the youth team, where he remains.

The most recent research from Fare and the Moscow-based Sova Centre reported a surge in racist incidents in Russian football, with most cases going unpunished. Researchers logged 92 incidents of discriminatory displays and chants by Russian fans in and around stadiums in the 2014-15 season, compared with 83 for the previous two seasons combined.
