MMA's Khetag Pliev Returning To Cage 4 Mos. After Finger Ripped Off Mid-Fight

Khetag Pliev literally had his FINGER TWISTED & RIPPED from the rest of his body 135 days ago during an MMA fight ... and now the crazy tough fighter is stepping back into the cage.

Remember, 37-year-old Pliev's fight against Devin Goodale was ruled a no contest after it was discovered that the digit had been severed sometime during the bout. For minutes, no one could locate Pliev's left ring finger.

Thankfully, the mangled finger was discovered tucked away in his glove ... and Khetag -- who has a 5-1 record -- was taken to a hospital where the finger was reattached.

And, good news, he says the finger is in working order.

So, MMA career dunzo, right? Nope.

Pliev is fighting Nah-Shon Burrell Saturday night at Cage Fury Fighting Championship 99 ... and when we talked to the 37-year-old fighter, it's clear he isn't the least bit concerned about the injury.

In fact, he promised a 1st round knockout.
