Khabib Nurmagomedov says he's going "The Walking Dead" route to make weight at UFC 219 -- telling TMZ Sports he'll hack off his own leg to hit 155 pounds in 10 days.

Don't worry -- he's kidding ... we think.

"I’m gonna cut my leg ... right or left, I don’t know," Khabib told us out in Century City.

On the real, Nurmagomedov says he's sick of everyone hating on his diet ... after a weight-cutting issue forced him outta his fight with Tony Ferguson ﻿back in March.

Speaking of Tony ... Khabib says he could whoop both Ferguson and Conor McGregor IN THE SAME NIGHT ... and he seemed dead serious about that, too.
