FIFA has opened an investigation into alleged racist abuse aimed at France players during Tuesday's international friendly with Russia in Saint Petersburg.
A pitchside photographer reported that monkey chants could be heard from the crowd during the game.
Racist chanting was also allegedly audible on a television broadcast after Paul Pogba scored France's second goal.
The game's world governing body said on Wednesday that it was collecting evidence and would contact the anti-discrimination Fare Network, which helps FIFA investigate racism cases.
"FIFA is collecting the different match reports and potential evidence in regards to the discriminatory incident reported in the media," a FIFA statement said.
"Until we have evaluated all information available, we cannot comment further."
