Real Madrid confirmed that Kylian Mbappé was diagnosed with a hyperextension of the posterior capsule of his left knee following medical tests conducted on 26 September 2026. The injury occurred during France’s 1-0 Nations League victory against Turkey in Kocaeli on 25 September, when Mbappé limped off shortly after scoring the match-winning goal.
France’s national team announced that Mbappé would return to Madrid for further assessment and treatment after departing the pitch due to the knee injury. Real Madrid’s medical report, issued a day after the match, did not specify a recovery timeline.
Real Madrid Medical Services stated: “After the tests carried out today on our player Kylian Mbappé by Real Madrid’s Medical Services, he has been diagnosed with a hyperextension of the posterior capsule of his left knee.”
Manager Zinedine Zidane expressed concern over the injury, saying at the time: “It’s not encouraging, so we’re not going to take any risks.” He added, “No, it’s not good. It’s not good, unfortunately.”
The diagnosis has been independently reported by Reuters, Associated Press, and Agence France-Presse, confirming the verified medical assessment detailed by the club. However, no official return date has been provided by Real Madrid, and speculation around specific match absences remains unconfirmed.
This injury could impact both Mbappé’s availability for France’s upcoming international fixtures and Real Madrid’s early-season plans. The extent of the hyperextension and ongoing assessments will determine how long the forward will be sidelined.
The next update is expected following further medical evaluations by Real Madrid’s health staff. CapeFlats.co.za will continue to monitor developments and provide timely updates on Mbappé’s condition and potential return.
