There are still several Ts that need crossing and Is that require dotting, but the UFC wants to put Georges St-Pierre and Nate Diaz inside the Octagon on the same night at the same event.

UFC president Dana White confirmed reports of the proposed bout during an appearance on UFC Unfiltered recently. The two would be the co-main event for the August UFC 227 event from Los Angeles that features Cody Garbrandt challenging TJ Dillshaw for the bantamweight title.

And that’s not all.

White also confirmed the promotion is working on a bout between former UFC middleweight champion Luke Rockhold and Alexander Gustafsson at 205 pounds.

“It is true, and (St-Pierre and Diaz) would fight at 155 pounds,” White said. “There are rumors that we were doing Gustafsson versus Rockhold. That is true, but that is not for the interim title. That’s false. It might be L.A. I’m targeting L.A. In my perfect world, if everything goes perfect, which nothing goes (expletive) perfect in this world: Dillashaw vs. Garbrandt, GSP vs. Diaz, Gustafsson vs. Rockhold and Derek Brunson vs. Antonio Carlos Junior.”

St-Pierre, a former UFC welterweight and middleweight champion, could be setting himself up for a run at a third title by competing at lightweight. He vacated the 185-pound belt without ever defending it following a victory over Michael Bisping late last year.

Diaz, meanwhile, has been on the sidelines since a 2016 loss to Conor McGregor via decision. He remains the only fighter in the UFC to defeat McGregor, submitting the former UFC lightweight and featherweight champion.
