A video shows the moment an amateur MMA fighter nearly scalped themselves after clattering the cage

• A new video shows the moment Hunter Boone suffered a fight-ending injury in an MMA match.
• The amateur fighter competed Saturday against Jordan Brown in Oklahoma.

A new video shows the very moment that amateur MMA fighter Hunter Boone almost scalped himself mere seconds into a match that took place last weekend.

Boone's head "slammed into the gate," said Boone's coach Jason Greer on Facebook, "resulting in the fighter suffering a 20-centimeter gash across his hairline."

He posted graphic photos of the injury on Instagram and it looked like a large flap of skin was so loose, it could be peeled back.

The incident took place Saturday at the Martial Combat 3 event at the FireLake Arena in Shawnee, Oklahoma.

Boone told Insider on Tuesday that he was still feeling the effects of the blow, and remained concussed.

He told us that he's "doing okay" and "taking it one day at a time," adding: "I'm still pretty out of it and concussed. I'll get with everyone when I can, man."

MMA Fighting obtained footage in which the injury allegedly took place.

The injury caused the fight to come to an abrupt end at the 17-second mark of the opening round.

In the video below you can see Boone's head appear to clatter the cage door during Jordan Brown's takedown.

Though they fight on the mat for some time after, the referee eventually intervenes to call time on the bout.

Brown was later announced as the winner of the fight.

Boone posted more photos of the incident on Instagram.

"I'm doing okay, taking a few days to rest up and recover," he said.

"Definitely a night I'll never forget. Talk to you all soon."

The gash required 17 staples to close, MMA Fighting reported Wednesday.

Greer called his fighter a "savage."

The coach said: "I love you, brother. I'm so proud of how you handled yourself. I know you'll be back to training and making a positive difference in everyone at the gym soon! Your family is behind you, brother."
