The 20-year-old's heart is functioning properly but tests cannot be conducted on the player's brain and he remains under supervision in hospital
Ajax have confirmed Abdelhak Nouri remains in an induced coma after collapsing during a friendly match against Werder Bremen.
Saturday's match at Lindenstadion in Hippach was abandoned after Nouri lay down on the ground, with paramedics tending to the 20-year-old after ambulances entered the playing surface.
Nouri was flown to hospital via helicopter and Ajax provided an update on his condition on Monday.
"Appie's heart is functioning normal and appears to be undamaged," Ajax said.
