South Korean footballer Lee Seung-Mo broke his neck during a K-League play-off game between Gwangju FC and Daejeon Citizen on Wednesday.
Lee went up for a header and landed on his neck in a horror fall that left the 20-year-old motionless on the ground.
He also broke his finger and lost his memory after being knocked out. Gwangju went on to lose the game 1-0.
Lee was quickly attended to on the pitch by medical staff and later rushed to hospital, where it was confirmed he had fractured three of his cervical vertebrae.
Remarkably, Lee is expected to make a full recovery having avoided any head injuries. He will spend at least a fortnight in hospital before a three-month recovery period.
Footage has emerged of the moment Lee broke his neck and it's a truly gruesome watch, so watch it at your own risk.
"He only remembers going for the header and then he lost his memory until he arrived at the emergency room," a club statement read.
"He regained consciousness after arrival at the emergency room in Yuseong-Sun Hospital. He complained of pain in [his] left and [his] back.
"There was no abnormality in the CT scan, only three fractures of the cervical vertebrae.
"He was transferred to the hospital of Chosun University in Gwangju that night and interviewed with a neurosurgery attending physician. The left-hand finger fracture was confirmed.
"He will be discharged from hospital two to three weeks after stabilisation and restoration because there are no other abnormalities. It will take two to three months to recover completely."
