UFC's Beneil Dariush Says He's Willing To Die In The Octagon To Beat Tony Ferguson

"You want to see a guy who's wiling to die in that Octagon? I think that's Tony and I."

That's UFC fighter Beneil Dariush telling TMZ Sports that he and Tony Ferguson are ready to sacrifice their lives in order to earn a victory at UFC 262.

Yeah ... heavy stuff.

We talked to the 32-year-old, #9 ranked Iranian-American fighter -- the co-main event Saturday night in Houston -- about the biggest fight of his life ... and what both men are ready to risk.

"I think two guys who are willing to go out there, if we have to leave in pieces, we'll leave in pieces, but we love the victory," Dariush says.

"I think that's one of the similarities that Tony and I have and I think that's one of the reasons why everybody should watch the fight.

FYI, Beneil is on a 6-fight win streak ... meanwhile 37-year-old Ferguson is in the midst of a 2-fight losing streak (Gaethje & Oliveira).

Regardless, Tony is still considered one of the most dangerous dudes in the lightweight division.

So, how does Dariush get the dub against El Cucuy?

"I think it can go all three ways. Knockout, submission or decision Whatever it is, I gotta stay one step ahead of him."
