It’s no secret that UFC President Dana White and lightweight star Nate Diaz have had their share of issues in the past - after all, Diaz once got to slap White - but when Diaz finally was set to return against Dustin Poirier at UFC 230, it looked like maybe their relationship would be back to business as usual. But now that Poirier has been removed from the card due to injury and Diaz has chosen not to accept a short-notice replacement, it looks like their cold war is back on in full.
