On 8 July 2017, Nouri collapsed during a friendly match against Werder Bremen, due to cardiac arrhythmia. He was taken to the hospital by a trauma helicopter, and his condition was announced as stable. Five days later, however, Ajax reported that Nouri had suffered severe and permanent brain damage as a direct result of the incident. Nouri eventually left intensive care on 25 July 2017, being able to breathe unaided, but will not be able to play football again. In June 2018, Ajax announced an investigation had found that the medical treatment Nouri received on the field was "inadequate" and he remains in coma. StayStrongAppie
