Ajax have announced that Abdelhak Nouri has severe and permanent brain damage following his collapse on the pitch while playing against Werder Bremen on Saturday.
Ajax made the statement on their official English Twitter feed:
AFC Ajax (English)Our thoughts and prayers go out to him and his loved ones in this difficult time. (2/2) #StayStrongAppie
Per BBC Sport, he was put in a medically induced coma after his collapse as a result of cardiac arrhythmia, but tests earlier in the week suggested he suffered "no heart or brain damage," with more thorough testing due to take place when he was conscious.
