That clears the path for Cormier and Miocic to have a rematch, slated for Anaheim on August 17 this summer.
He waited for Lesnar but White's verdict that the Canadian 'is done' means he'll have to face Miocic once more.
The former champion is one of the most decorated heavyweights in the history of the sport and the 36-year-old successfully defended his belt three times before meeting Cormier.
Neither fighter has an objection to the rematch and negotiations should pass smoothly.
