After Eriksen collapsed on Saturday, the match was suspended following prolonged efforts from the medical staff to resuscitate him with CPR and a defibrillator. Players from both teams were visibly distressed as he was being attended to by medics.
He was taken to a nearby hospital where he was reported to be in a stable condition.
