Wrestler Nick Gage 'died for seven minutes' after a particularly deathly Tournament of Death match.
The 40-year-old was fighting German wrestler Thumbtack Jack in 2009 when he was thrown through a wall of tubing surrounding the ring. But it quickly became apparent that something had gone badly wrong as blood poured from Gage.
A shard had severed an artery and he had to be transported to hospital in a helicopter, during which period he temporarily passed away.
His extremely close run in with death was discussed in Dark Side of the Ring: The Ultra-Violence Of Nick Gage. Watch a trailer here:
Speaking in the documentary, Gage said: "I get in the helicopter, that's the last thing I remember.
"The nurse had said, 'You flatlined while you were in there and the doctors brought you back because you lost too much blood'."
Fellow wrestler Jon Moxley added: "A guy like Nick Gage to just get up and walk off like that? You know it had to be serious.
"He was legally dead for seven minutes.
"He died at a Tournament of Death. It's supposed to be turn of phrase, you're not actually supposed to die.
"He did. It just cements and solidifies Nick Gage's spot as folk hero."

Last year, a documentary series about WWE's Deadman had wrestling fans captivated.
Five-part series Undertaker: The Last Ride gave fans an unprecedented behind-the-scenes look at the iconic wrestler during the final chapter of his career.
The documentary featured out-of-character interviews with the big man himself, as well as the likes of his wife and former Divas Champion Michelle McCool, and stars such as Vince McMahon, Shane McMahon, Paul 'Triple H' Levesque, John Cena, Roman Reigns, Batista, Ric Flair, Edge, Shawn Michaels, Mick Foley and many others.
The series culminated with the 56-year-old wrestling legend calling time on his glittering career - seemingly for good this time.
He said: "I believe I'm at a place now, post-Boneyard, which was a hellacious battle against one of the best in the business. Here you are, climbing on your motorcycle and taking off.
"There was a lot of thought and a lot of emotion, one of those being, 'Are you happy enough with that?' It was a powerful moment. You don't necessarily always get those. If there was ever a perfect ending to a career, that right there was it."
