A matador is in serious condition in intensive care after he was gruesomely gored by a bull in Spain on Saturday, according to local media reports.

Young bullfighting star Gonzalo Caballero, 27, suffered a seizure and had to be sedated after he was gored in his femoral artery — causing him to lose 3 liters of blood, Madrid newspaper El Pais reported.

Caballero’s girlfriend Victoria Federica, niece to the king of Spain, looked on in horror from the stands of the famous Las Ventas square as Caballero was rushed out of the ring by fellow matadors — leaving a trail of blood behind him as he clutched his thigh to stem the bleeding.

According to El Pais, surgeons operated on the matador in the Madrid bullring’s infirmary and found severe damage — including an 11-inch-deep wound to the artery, which is a major blood source.

Caballero was moved to the intensive care unit of Francisco de Asis hospital, where he remains sedated and on a breathing machine, according to the report.

The young matador had only just returned to the ring after being gored in the same bullfighting square on May 23 — spending weeks in the hospital and sharing photos of himself learning to walk on crutches.

The bull that charged Caballero was covered in its own blood after being speared several times in the back, as is tradition in bullfighting.

Caballero was then given the severed ear of the bull, which was cut off by another matador in front of the crowd to be kept as a souvenir, another tradition.

Bullfighting continues to draw significant crowds despite being condemned by PETA, which estimates at least 7,000 bulls are slaughtered each year in Spain’s bullrings.
