Joe Rogan has revealed the 'most gruesome' injury he has ever seen in MMA as doctors compared it to a car accident.
Rogan was joined by UFC contender Michael 'Venom' Page on the latest episode of his podcast and they discussed several topics in MMA, including the fighter's ascent to stardom.
Page made his name under the Bellator banner before joining the UFC.
He spent over nine years in Bellator, beating the likes of Paul Daley and Douglas Lima.
Page also boasts a sensational victory over Evangelista 'Cyborg' Santos, knocking him out in the second round of their welterweight clash with a devastating flying knee in 2016.
The Brit cracked Santos flush on the forehead, fracturing his skull in the process.
Naturally, his victory over the Brazilian was brought up in his chat with Rogan, who recalled the devastating finishing move.
Rogan described Santos' fractured skull as the 'most gruesome' injury he has ever seen in the sport.
"That was the most gruesome injury I've ever seen," said the UFC commentator. "I've seen a lot of broken bones. I've never seen someone with a caved in head."
According to Page, doctors said they have only seen similar injuries in car accidents.
"The doctors were saying... they said he's only ever seen that in a car accident. Never in MMA," he revealed.
Rogan added: "That is so crazy. How could you fight again? It sounds like a baseball bat on a pumpkin."
Page celebrated his victory over Santos with a Pokemon-themed celebration unknowing he had fractured his opponent's skull.
On his celebration, he said: "I felt very bad at the time."

"My recovery was very uneventful, thankfully," he said in 2017. "I remained in Houston, Texas, for six months. Whenever possible, I’d go back to the hospital for follow-ups. I’ve been in Brazil since December.
"My recovery went very well. I never felt anything. I don’t feel anything. The decision to remain 'suspended' from fighting came from me. I believe I need this time to recover. I have to respect my body.
"It was a very serious fracture, as everyone saw."
