Spain's only English bullfighter Frank Evans is likely to retire nearly 40 years after killing his first animal.
Frank Evans killed his first bull when he was 17
Frank Evans, from Salford, Greater Manchester, is suffering from a knee problem which will require a major operation and fears his career is over.
Mr Evans, known as El Ingles, killed his first bull in 1966 aged 17.
He is one of very few English matadors to ever work in Spain, with the activity branded cruel by many outside the Iberian peninsula and France.
Mr Evans, 57, said continuing after he has a prosthetic knee inserted could be dangerous: "You need all your faculties. I've been fighting for the last two or three years with this problem developing, but it's coming to a point where I'm becoming more vulnerable."
Regarded as a novelty
He said he had always been regarded as something of a novelty in Spain, but had enjoyed his career.
"When I first announced to Spain that I wanted to be a matador, they were curious and they've never ceased to be curious.
"If you announce you want to fight bulls and you're from a country where bullfighting is not traditional they probably don't think you could have the passion and the style you need to be a matador.
"I don't think you'll ever convince them really but it's been great fun trying."
Fighting in Mexico, Venezuela and France had been career highlights along with his becoming a full matador in 1991, Mr Evans said.
