Former world champion boxing coach Enzo Calzaghe has had his training licence withdrawn by the British Boxing Board of Control.
The 63-year-old, one-time coach of son Joe Calzaghe, had his licence of 30 years revoked for failing to complete their mandatory first aid course.
Calzaghe's licence issue is a blow for Enzo Maccarinelli.
The Welsh fighter can now not have Calzaghe in his corner for his British Cruiserweight title shot on Friday.
Calzaghe maintains he has undertaken a St John Ambulance first aid course.
But the British Boxing Board require all trainers undertake their own one-day first aid course before they can be granted a licence to coach boxers.
Calzaghe helped his unbeaten son Joe rule the super-middleweight division for 10 years before stepping up to become the world's top light-heavyweight by beating legendary Americans Bernard Hopkins and Roy Jones Jr in the United States.
The Italian coach also trained Maccarinelli and Gavin Rees when both were cruiserweight and light-welterweight champions respectively. He took a break from boxing when Calzaghe Jr retired in 2009 but has since returned to boxing and been reunited with Maccarinelli.
The 31-year-old has earned a British title shot against champion Shane McPhilbin in Wolverhampton's Civic Hall on Friday but will now not have the experienced Calzaghe in his corner.
Maccarinelli will be assisted by his brother Valentino and respected boxing corner-man Dean Powell.
Calzaghe's absence, says Maccarinelli, will have no bearing on the eventual outcome.
"I'm blanking that out," he insisted. "I've done the training, we've worked well together in the gym and I feel a million dollars.
"But in the ring it will be me and Shane McPhilbin - my corner can't help me, his corner can't help him." Also related to this story
