Tottenham's FA Cup game against Bolton Wanderers has been abandoned after Trotters midfielder Fabrice Muamba collapsed and stopped breathing.
Medics spent 10 minutes trying to resuscitate the 23-year-old on the field before the players were called off by referee Howard Webb.
BBC Radio 5 live senior football reporter Ian Dennis says the midfielder is fighting for his life.
The score was 1-1 when he collapsed with no players close-by on 41 minutes.
Medical staff gave him mouth-to-mouth resuscitation and tried to revive him with a defibrillator. In total six medics were treating the player.
Muamba was taken off the pitch on a stretcher and ESPN reported that he was not breathing as he was taken down the tunnel. The former Arsenal midfielder has been taken to hospital.
Referee Webb called the visibly shaken players off the field after consulting with managers Owen Coyle and Harry Redknapp. Minutes later the match was abandoned.
