Thousands of spectators watched in horror as Israel Lancho was attacked by the sixth bull at the Las Ventas bullring in the capital.
Reports said Mr Lancho reached the bullring surgery still conscious despite being speared by one of the bull's horns.

gored during a bullfight in Madrid.
The 30-year-old had emergency surgery under general anaesthetic on the 25cm-deep wound sustained upwards in the chest area.
The Daily Mail said his gaping wound was nearly eight inches wide, with Spanish press claiming it was a miracle the bull's horn had missed his heart.
The bullfight was held as part of Madrid's annual San Isidro fiesta, which honours the city's patron saint.
Local media reported the matador was in a very serious condition at the Clinica Virgen del Mar in the Spanish capital following the surgery.
