Devin Clark sustained one of the most gruesome injuries you'll ever see in a combat sports event ... and now the UFC fighter is answering the question -- how much it did hurt?!?
"It was probably a 7 or 8 after the fight. You fight the fight. He got his hand raised. Then that adrenaline starts coming, and it comes down quick. And, by the time I'm leaving the cage, I'm like, 'Okay, that hurts,'" Clark tells TMZ Sports.
If you didn't see the injury (lucky you) ... it was incredibly gross. Devin was fighting fellow light heavyweight fighter Ion Cutelaba at UFC Fight Night Saturday afternoon.
