Justin Gaethje is booked to fight Dustin Poirier on Saturday night, but it sounds like the lightweight contender has bigger issues with James Vick.

Gaethje will battle Poirier in the headliner of UFC on FOX 29, which will go down in Glendale, Arizona. But, while speaking to MMA Junkie recently, the former WSOF champ had some choice words for Vick:

“That dude needs to get slapped,” Gaethje said. “He called me a b-tch on the Internet, so when I do see him, I’m going to slap the f-ck out of him. I am not happy with him.

“It’s like seeing a little kid that just won’t shut up because their parents won’t spank him. It gets old.”

Chances are we’ll see Gaethje and Vick throw hands at some point in the Octagon. First things first, and that’s getting by Poirier, who is one of the more dangerous 155’ers on the UFC roster. “The Diamond” has a nasty straight left and is no slouch on the ground either.

Gaethje will be fighting for the first time since he was taken out by Eddie Alvarez in December.
