The Daily Express says Muamba could make an astonishing return to top-flight football after being "wired up" with a life-saving device.
The 24-year-old midfielder has now been fitted with an electrical implant that will kick in if he ever has another cardiac arrest.
In 2004, former Bolton midfielder Khalilou Fadiga, became the first professional footballer to wear an ICD after he collapsed - ironically before a game against Tottenham.
He recovered to play nine times that season and appeared 21 times for the club in his two-year stay.
Last night Fadiga, now 37 and living in Belgium, said: "I wanted to play again and I did have a career and didn't have any more problems with my heart. Bolton gave me the confidence to carry on and I will always thank them for that."
