The French Rugby Federation (FFR) has suspended full-back Melvyn Jaminet for 34 weeks and fined him 30,000 euros (£25,335) after he posted a racist video on social media.
During France’s summer tour of Argentina earlier this month, the 25-year-old posted the video, which included a racist comment aimed at the Arab community.
In a statement, the FFR said Jaminet had “harmed the best interests of rugby”.
The Toulouse full-back can reduce his ban by eight weeks by taking part in anti-discrimination activities to “promote the values of sport”.
Completion of those activities would free Jaminet to be available for selection before the start of the 2025 Six Nations.
Jaminet, who was sent home from the tour, has said he is “deeply sorry and ashamed of my comments”.
In a post on Instagram, he added: “Racism, in all its forms, is unacceptable and goes against everything I believe in.
“I understand the FFR’s punishment and remain at their disposition to be able to shine a light on this incident.”
The day after Jaminet posted the video, his France team-mates Hugo Auradou, 20, and Oscar Jegou, 21, were charged with the aggravated rape of a 39-year-old woman.
