Marcus Thuram joined an array of sporting personalities in protesting racism in the United States when he took a knee after scoring for Borussia Moenchengladbach in the Bundesliga on Sunday.
Thuram's gesture echoed past protests by National Football League players in the US in support of the Black Lives Matter movement.
The issue has surged back into the headlines following the death of George Floyd in Minneapolis.
Thuram's gesture was the second protest in the Bundesliga this weekend.
The 22-year-old French striker continued his recent hot form with two goals as Borussia Moenchengladbach beat visiting Union Berlin 4-1.
Because of social distancing rules, goal celebrations were muted but after Thuram headed his team's second goal just before half time he took the opportunity to make a solitary statement, kneeling and bowing his head.

At half time, his club tweeted a photo with the caption: "No explanation needed." After the game, Gladbach coach Marco Rose said Thuram had his backing.
"Marcus has made the point. He has set an example against racism that we all support," Rose said.
Thuram, whose father, French World Cup winner Lilian runs the Education against Racism foundation in Paris, was the latest show of solidarity with the current protests sweeping the United States.
