Bobby Green Says Taking Short Notice Fight Vs. Islam Makhachev Is ‘F***ing Nuts’

UFC star Islam Makhachev needed an opponent after Beneil Dariush suffered a freak injury while training … enter MMA vet Bobby Green, who took the fight on JUST 10 days’ notice.

Why take a fight against a guy who hasn’t lost in 6.5 years?! TMZ Sports asked Green.

“I know, I know. It’s f**king crazy. Put the weight on, take the weight off, just fought, come back and fight again. I’m f**king nuts brother, this is what I do. I try to show everybody that this is real s**t. I call it G s**t, you know, doin’ things that most people won’t do.”

Savage.

What makes it even crazier is that Green just fought on February 12 against Nasrat Haqparast at UFC 271 … where he won via unanimous decision.

Now, Bobby will step into the Octagon with Makhachev, the man many believe will be champion before 2023 rolls around.

Islam has just 1 loss on his professional MMA record — in October 2015 — and has won 9 straight, including wins over Drew Dober and Dan Hooker, which IM made look easy.

But, Green isn’t just stepping up to exchange an L for a fat paycheck … he tells us how he’s going to beat the 4th ranked lightweight.

We also talked to Islam … who told us he actually respects Bobby for stepping up (and he tells us who turned down the fight).
