"I said, 'Wait a second, where the f*** is his finger?' They were all like, 'I don't know.'"
That's how one witness described seeing an MMA fighter LOSE A FINGER mid-match Thursday night ... and, yeah, the injury was just as horrific as it sounds.
During Khetag Pliev's bout with Devin Goodale at Cage Fury Fighting Championship in Philadelphia, officials had to stop the fight when they noticed Pliev was missing a freakin' finger.
The images were INSANE ... video of 37-year-old Pliev in his corner showed the ring finger on his left hand had been completely severed at some point during his match.
