Brann midfielder Carl-Erik Torp suffered a suspected heart attack towards the end of his side's Tippeligaen clash with Sogndal, according to reports in Norway.
Torp, 27, collapsed shortly after coming on as a substitute and was airlifted to hospital.
"He suffered a cardiac arrest. We cannot say anything more yet other than that right now he is stable and doing well.
"We got him going again and he is in good hands.
"We used a defibrillator and CPR on the way off the pitch. When he was taken off by air ambulance, he was stable and conscious."
