The FA Cup tie between Tottenham Hotspur and Bolton has been abandoned after player Fabrice Muamba collapsed on the pitch.

The 23-year-old Bolton midfielder collapsed with several minutes remaining in the first half. Players rushed to his aid and looked on in horror as medics worked to resuscitate him.

The former England Under-21 star was taken off on a stretcher as fans held their heads in their hands, with some in tears.

Referee Howard Webb called off the match after the incident.

Reporters at the scene said the player had stopped breathing and has been taken to hospital.

Commentating on ESPN, John Barnes said: "From the players' reaction on both sides it seemed that things were pretty serious."

Kevin Keegan added: "Jermain Defoe seemed absolutely distraught. The fans are in a state of shock. I've never seen anything like that on a football pitch before. Our hearts go out to his family."

There was nobody around Muamba when he went down and he was not involved in a challenge.

Bolton manager Owen Coyle ran on to the pitch to see what had happened as players gathered and a defibrillator was used on the star, who has also played for Arsenal and Birmingham.

As a message was relayed around the stadium that the game was off, the fans applauded and chanted Muamba's name. The scene recalled memories of Cameroon's Marc Vivien-Foe who collapsed and died during a Confederations Cup match in 2003.
