Embattled UFC lightweight Nate Diaz offers to move back up to 170 pounds to fight Matt Brown

Fresh off his "Immortal" beatdown of Erick Silva last weekend in Cincinnati (watch it), streaking Ultimate Fighting Championship (UFC) welterweight Matt Brown was hoping to score a "legendary" mixed martial arts (MMA) fight against former division number one contender Nick Diaz.

Sorry, he's retired.

But willing to step in and take his place is younger brother Nate Diaz, who finally found a fight that interests him. So much so, that he's even willing to abandon his post at 155 pounds to move up in weight (again), according to his conversation with MMA Fighting, so that he can fight one of the "baddest motherfuckers out there."

His words:

"I want the Matt Brown fight. That's what I'm looking for. I'm trying to fight the baddest motherfuckers out there. I'm not trying to fight some lame ass fighter that they're trying to build off of me. My brother is retired. So if this guy wants to fight a Diaz, he's got to fight me."

Brown has yet to issue a response.

Diaz has been riding the pine since a technical knockout win over Gray Maynard last November. His inactivity cost him a spot in the lightweight rankings and UFC President Dana White has refused to budge on The Ultimate Fighter (TUF) 5 champ's growing list of demands.

Unfortunately, the fight doesn't do anything for the red-hot Brown.

After winning seven straight (with six finishes), he's perhaps just one win away from a 170-pound title shot. Would a Diaz fight be too much to risk at this point in his combat sports career? Probably, but it sure would be fun to watch.

Anyone disagree?
