Nate Diaz will face Josh Thomson tonight at UFC on FOX 7 at lightweight.

Following the contest, Diaz could be headed back to the welterweight division, as he told recently.

Diaz (16-8) competed for the UFC 155-pound title last year, but was unsuccessful.

“I don’t think there’s anything for me at the lightweight division,” Diaz said. “I already beat everyone at lightweight or I fought everyone already. The only person who beat me was Ben, and Gil’s (Melendez) going to handle him Saturday. I’m going to sit around and fight the guys all over again? Boring. There’s no motivation in that. I’d rather fight someone new.”

Diaz went 2-2 a couple years ago when he competed at 170, falling to contender Rory MacDonald. He is 11-6 in his UFC career, and added that “unless (the promotion has) something really cool for me to offer (at 155), or a really cool fight that would interest me, yeah, I’m out.”

So, could we see Diaz vs. Diaz, as Nick is also a welterweight? Highly, highly, highly doubtful….but cool to think about.
