"I have no words; I can't believe it," said Juan del Álamo, the bullfighter who eventually killed the animal that had gored Fandiño.
"He was in a lot of pain from the goring, but nobody expected it to end up like this. None of us understand how it could have happened; it was all so fast. The bull knocked him down with its hindquarters and he fell face down," Mr Del Álamo told television cameras.
The fatal goring of Víctor Barrio last July in Teruel, Spain, led to controversy as some animal rights supporters expressed their joy at his death on social networks.
Barrio was the first Spanish bullfighter to have been killed in action since 1985.
According to Spanish newspaper El Mundo, Fandiño had to be reanimated after suffering a heart attack while in the bullring's surgery. A second heart attack reportedly ended his life in the ambulance.
