Zinedine Zidane's first game in charge of France ended on a sour note as Kylian Mbappe injured his left knee moments after scoring in a 1-0 win in Turkey.
Michael Olise threaded a fine pass and the World Cup's all-time leading scorer Mbappe rifled in a low shot in the 54th minute.
Mbappe then sat on the ground clasping his left leg and within minutes Zidane had to take him off.
The France camp said he suffered a knee tendon injury and would return to Madrid for treatment. A replacement was not immediately named.
“No, it’s not good. It’s not good, unfortunately,” Zidane told French television about Mbappé's injury. “We will not take risks.”
Mbappé was on the left flank and fellow Ballon d’Or contender Ousmane Dembele through the middle in Zidane’s first line-up, with Olise on the right wing and Manchester City's Rayan Cherki in midfield.
A scrappy opening saw lots of botched passes from both sides, although the bumpy playing surface at Kocaeli Stadiuma stadium in İzmit was a factor.
Near the end of the first half, Olise's dipping shot forced a fine save from Ugurcan Cakir and midfielder Adrien Rabiot scooped the ball over following fine work from Cherki and Dembele.
France goalkeeper Mike Maignan matched Cakir's save with a stunning one-handed stop from Ismail Yuksek’s downward header. Cakir was then sent off in the 87th for blocking Bradley Barcola's shot with his arm when he was outside the area.
