His brother, Nick, may be dominating headlines thanks to a positive drug test and looming suspension but Nate Diaz has a big fight coming up against Jim Miller in the main event of UFC on Fox 3 on May 5 in New Jersey.

And he's the underdog.

According to noted oddsmaker Nick Kalikas on his MMAOddsbreaker show, Diaz is the +190 dog to Miller, who opens as the -250 favorite for their lightweight bout that should serve as a number one contender match.

Diaz has won his last two bouts since making his return to the 155-pound waters, besting both Takanori Gomi and the streaking Donald Cerrone. The latter victory put him in title contention and a win over Miller could very well push him over the top.

It won't be easy, of course, considering the New Jersey native's track record. Though he recently dropped a hard-fought decision to Ben Henderson in a bout he was dealing with sickness for, Miller is still 8-1 in his last nine bouts, including a first round submission over Melvin Guillard just last month.

Considering the platform, it being the third network televised event and these two occupying the headlining slot, the winner could have a title shot awaiting him on the other side.

Stay tuned.
