Nate Diaz talked about a potential return to welterweight last week before his match with Josh Thomson.

After seeing Thomson handle the former No. 1 contender to the UFC lightweight title, UFC president Dana White was asked about the shift in weight classes.

“I think going to 170 is a big mistake,” White said. “(There are) big, strong guys at 170.”

Thomson stormed after Diaz, who has now lost two in a row. He is 9-5 at 155 pounds with the UFC, and went 2-2 during a welterweight run a few years ago.

While the chance of another crack at the belt is likely several steps away for the Stockton fighter, would he have any shot at working through the ranks of 170?

Headed by Georges St-Pierre, Johny Hendricks, Jake Ellenberger, Rory MacDonald, Demian Maia, Carlos Condit and even Nate’s brother, Nick, all call welterweight home and are Top-10 fighters.
