Kylian Mbappé scored the winner in Zinedine Zidane's first match as France coach, then limped out with the Mbappé injury that will keep him out of the rest of the international break. The captain hyperextended his left knee on the shot that beat Türkiye, briefly tried to continue, and was substituted minutes later as France opened its Nations League campaign with a win in Istanbul.

The goal arrived in the 55th minute. Michael Olise threaded the ball through for Mbappé, who rifled a low shot past the Türkiye goalkeeper to break the deadlock. It was the 27-year-old's 67th international goal, and the Mbappé injury came with no opponent nearby and no challenge involved. He landed awkwardly on the strike, immediately felt pain in his left knee, and sat on the turf rubbing it before the medical staff reached him. Mbappé briefly returned to the pitch, went down again within a minute, and Désiré Doué came on in his place. He walked off the pitch under his own power, according to ESPN.

The French Football Federation confirmed the Mbappé injury in a statement after the match, saying he had suffered a tendon injury and would miss the rest of the camp. He left the national-team base and returned to Real Madrid for assessment.

What the medical scans showed

Real Madrid followed up with its own statement on Saturday with more detail on the Mbappé injury, diagnosing a posterior capsule hyperextension of the left knee. A hyperextension describes the mechanism rather than the full extent of the damage: the joint straightens beyond its normal limit, and the immediate consequence is often tendon damage, which can range from irritation to a full rupture. Dr Jean-Bernard Fabre, a sports science doctor, explained the mechanism in Le Parisien, noting that the tibia is driven forcefully backwards beyond what the joint can normally allow.

According to reporting in Spain, there is no major alarm inside the Madrid camp about the Mbappé injury. Spanish media have suggested the France captain could be back within two weeks, which would mean he does not miss a competitive match for his club. The early reading is precaution rather than panic, although the full timeline will depend on how the knee responds to treatment over the coming days.

A debut win that Zidane cannot fully celebrate

The injury overshadowed what Zidane needed most: a winning start. The former midfielder took charge of France after Didier Deschamps stepped down following the World Cup, and he started Mbappé on the left wing with Olise on the opposite flank and Ousmane Dembélé alongside Rayan Cherki in an attacking quartet, on a bumpy surface at the Kocaeli Stadium in Izmit. The goal settled it.

France held on after Türkiye were reduced to ten men late on, goalkeeper Uğurcan Çakır dismissed in the 87th minute for handling outside the penalty area. The 1-0 scoreline was enough to open the Nations League campaign with three points, and the three points matter for a group that also features Belgium and Italy.

Zidane made his priorities clear when asked about the Mbappé injury after the final whistle. He told French television the situation was "not good" and "not very encouraging," and said Mbappé would have to return to Madrid because France would take no risks with him. It set the terms for the rest of the window: no Mbappé against Belgium in Brussels on Monday, and none of him for the October fixtures either. The injury was first detailed by ESPN, and the French federation's decision to release him was carried by Reuters.

The timing is awkward for club and country alike. Mbappé has been scoring freely for France this year, and the Mbappé injury leaves Zidane without the side's leading scorer at the start of a campaign that will define his early tenure. France's medical staff will now hand responsibility to Madrid's, and the next update will come from the club. For Zidane, the debut delivered the result; the bill came in the shape of his captain's left knee.
