The Diaz brothers are finally back together in the UFC. After an 18 month suspension by USADA for a positive marijuana test, Nick Diaz is eligible to fight again in the UFC. Diaz tested positive after his fight against Anderson Silva in January 2015.

But now, Diaz, who has been spending his time supporting his brother Nate in his fights, is ready to step back into the octagon. However, there's a caveat: he's only interested in big fights.

"We're going to have to sit down and see what the fans want to see," Diaz said to ESPN.com. "I'm on top right now. There ain't no giving me a shot. I'm giving somebody a shot. If anybody's getting a shot, it's somebody getting a shot against me. I'm the guy to beat because I don't need nothing. I'm fine the way I am.

"I don't need a fight. I don't come and fight for fun. I don't do that. I don't like to hurt people for fun."

Diaz also noted he's not interested in a fight with now former champion Robbie Lawler because he just lost.

"I don't see a superstar out there. I don't see Georges St-Pierre coming back. He's too scared to come back and do a fight with me and the rest of these guys are not superstars. Who are they?"

Diaz, 33, is 26-9-2 in his professional MMA career. He is 0-2-1 in his last three fights, including unanimous decision losses to Georges St-Pierre and Carlos Condit.

Diaz was originally suspended five years for the positive marijuana test, but had his suspension reduced by the Nevada State Athletic Commission in January after the two sides reached a settlement.
