Bullfighter Antonio Romero was gored in the anus by a bull on March 19 in Mexico City, Mexico.
While the video of the incident may not look unusual for bullfighting, the bull's horn briefly went into Romero's anal area while the matador was on the ground, reports the Daily Mail.
The crowd screamed with horror as the 1,160-pound bull, named Caporal, gored Romero.
His injuries were originally noted as "severe" at a local hospital, but turned out to be very extensive.
Dr. Rafael Vazquez Bayod told Univision (translated by SB Nation) about Romero's injuries: "The goring is very serious, very serious, a very, very severe injury in the anorectal region. It was a very powerful horn that completely destroyed the anal sphincter and seriously damaged the rectum."
Romero's rectum sustained an injury 11.8 inches deep, which required more surgery than originally planned.
On March 20, doctors had to fully reconstruct Romero's anus and rectum.
There's no word on what happened to the bull, which had several spears stuck in its body in the video.
The Los Angeles Times reported in April 2016 that bullfighting is a controversial spectacle in Mexico.
The newspaper referred to a 2015 Parametria poll that found 73 percent of Mexicans citizens supported a nationwide ban on bullfighting, which is viewed as cruel and outdated.
However, bullfighting is only banned in the Mexican states of Sonora, Coahuila, which bored the U.S., and Guerrero. In Mexico city, where bullfighting remains popular, there's the largest bull ring in the world, seating 48,000 spectators.
According to Humane Society International, bullfighting is legal in Colombia, Ecuador, France, Peru, Portugal, Spain, Venezuela and Mexico -- where there are an estimated 225 bullrings.
HSI opposed bullfighting, and describes it as an "agonizing death" for the bull:
The object of bullfighting is for the bullfighter (matador) to "conquer and kill the bull with a swift clean kill by placing a sword in a coin-sized area between the bull’s shoulders."
Advocates of bullfighting argue that if the matador aims correctly, the animal dies in a matter of seconds. This type of quick, clean death, however, is not the norm. In most cases, the matador misses the target, injuring the bull’s lungs and bronchial tubes, causing blood to flow and bubble through the animal’s mouth and nose.
In every bullfight, or “corrida de toros”, four to six bulls are killed. Each bullfight is split into three "tercios," or thirds, with two bullfights per session, each lasting about 20 minutes.
