Experts doubt Bolton Wanderers midfielder Fabrice Muamba will play again.

Peter Weissberg, the Medical Director of the British Heart Foundation, believes Muamba's sudden collapse means he can never truly be cleared to compete in the future - even if he makes a full recovery.

He said: "It is not possible to say but I think it is likely he would be advised not to play again because most conditions like this are a combination of physical activity and an underlying tendency to have a cardiac arrest."
