Ivan Fandino, 36, who was a professional matador for 12 years, was performing at the Aire-sur-l’Adour bullfighting festival in the town of Mont de Marsan, near the Spanish border.
The Basque fighter fell to the ground after tripping on a cape used in a turn to engage and distract the specially-bred fighting bull, and the animal plunged one of its horns into the matador’s side, Spanish news agency EFE reported.
Hospital authorities declined to comment but an independent medical source said that Fandino had suffered two heart attacks in an ambulance and died later in hospital.
Fandino is the second Spanish bullfighter to die in the ring in the past year.
Victor Barrio was killed after being gored by a bull in front of spectators last July, the first time since the early 1990s a professional matador had died in the ring in Spain.
