Nate Diaz's brother Nick has taken a swipe at Conor McGregor's preparations ahead of Saturday night's fight in Las Vegas.

The 32-year-old is currently serving an 18-month ban from the UFC for marijuana usage but is helping prepare his younger brother ahead of the McGregor fight.

In the latest UFC Embedded video, Diaz has ridiculed McGregor's preparations for the fight, especially with movement coach, Ido Portal.

Diaz was comparing his brothers preparations with striking coach Richard Perez, compared to what McGregor was doing with Portal. "They have a f***ing guy swinging a fucking pool noodle at you, smacking you in the face with it, trying to promote his own shit. It’s a joke."

The two men meet in Las Vegas on Saturday night.
