Doctors have declared retired boxer Hector 'macho' Camacho brain dead after he was shot in the face on Tuesday (20Nov12), according to reports.

The former world champion was hospitalised in his native Puerto Rico after he was gunned down while sitting in a Ford Mustang car outside a bar in Bayamon.

The driver of the vehicle, Alberto Mojica, died at the scene and Camacho was said to be in critical condition at the Rio Piedras Medical Center in San Juan, where he was being treated for wounds to his face and neck.

Doctors have since revealed the bullets were deflected by the sportsman's jaw and subsequently hit his spinal cord.

His health further deteriorated in the early hours of Wednesday (21Nov12) when he suffered a heart attack and now he is facing a dismal future, according to local paper El Nuevo Dia.

Newspaper editors claim the 50 year old has been taken off life support and one medic tells the publication, "His recovery would be a miracle. Medically, there is nothing we can do."
