Ajax midfielder Evander Sno has been taken to hospital after suffering a suspected heart attack during a reserve match.
It has been confirmed that Sno, 23, collapsed on the field after 63 minutes of Monday's game against Vitesse Arnhem and was taken to a hospital nearby.
Sno, who has previously played for Celtic and spent time on loan with Bristol City last season, was resuscitated on the pitch by the medical staff of both clubs. A defibrillator had to be used three times and the official Vitesse website says this "probably saved Sno's life".
The match was then called off, and Vitesse chairman Ted van Leeuwen said the player was in a stable condition when the ambulance arrived to take him away from the stadium.
An Ajax spokesman said: "He is now conscious. Evander is breathing again and can now talk again."
Several footballers have died of heart attacks in recent years, including Marc-Vivien Foe, Antonio Puerta and Dani Jarque.
