UFC 158: Nate Diaz Posts New Event Photo, Rips GSP for Rumored Steroid Use

Apparently, the Diaz brothers still have a sense of humor.

While Nick Diaz's younger brother Nate won't be fighting at UFC 158, the veteran lightweight contender is nonetheless fulfilling his usual duties as cornerman, bodyguard and entourage.

But as much work as that might entail, there's always time for the Stocktonians to poke fun at welterweight champion Georges St-Pierre.

During the UFC 158 pre-fight conference and a subsequent interview with SportsNet 590 "The Fan," Nick made headlines around the MMA world when he openly accused GSP of using steroids to gain an edge over his opponents.

As with most things that the older Diaz brother has said this week, the news caught like wildfire, raising the grim specter of drug use in mixed martial arts.

(Note: St-Pierre has never tested positive for banned substances.)

But even with rumors about GSP's drug use once again out in the public, Nate threw another not-so-subtle jab toward the champion's way with an alternate take on a UFC 158 poster.

Taking an obvious cue from the brothers' infamous support of medicinal marijuana, the imagery also points a finger at St-Pierre's suspected doping with a prominent syringe.

But all joking from the Diaz brothers aside, the trash-talk and mind games may come to end after the main event of UFC 158, where Nick remains a heavy underdog to upset the second-longest active reigning champion in the promotion's ranks.
