Nate Diaz may not have been involved in the boxing mega-fight between Conor McGregor and Floyd Mayweather, but his presence loomed everywhere in the lead-up to Saturday night's tilt in Las Vegas. That said, the younger Diaz brother also made his mark on the evening with some post-fight ruckus with former UFC heavyweight turned Showtime commentator and McGregor enthusiast Brendan Schaub.

The two men crossed paths backstage at T-Mobile Arena, where they began talking about Mayweather's path to victory over the Irishman. Schaub felt the UFC lightweight champion took several rounds, to which Diaz contested those were not earned rounds because the pound-for-pound boxing great simply allowed it to happen rather than McGregor taking them.

This started a tense exchange between Diaz and Schaub, and fortunately for you the whole thing is posted on Instagram.
