While there will always be rumours around when a return might come, White identified his current time frame as "probably early next year."

Mixed martial arts has taken huge strides in Oceania over the past two decades to the point where nine fighters from the region are ranked inside the top 15 of their respective divisions.
This weekend, Adesanya and Volkanovski headline the UFC's biggest card of the year and the biggest for the Oceania region as they defend their belts, while No14-ranked lightweight Brad Riddell takes on Jalin Turner in the featured prelim - seen as the appetiser or 'final selling point' for the main card, which is on pay-per-view.
"If you look back (20) years ago, we had Elvis Sinosic. We had one guy from Australia. Now, there is tons of talent coming out of Australia and New Zealand, and you have to main event and co-main event coming out of Australia and New Zealand. It couldn't be a better time for your part of the world."
Should Adesanya get past Jared Cannonier on Sunday afternoon, he will likely know who his next challenger will be, with a high-level middleweight bout between No4-ranked Sean Strickland and kickboxing phenom Alex Pereria - who is still green in his mixed martial arts career with a 5-1 record, but has been put on the fast track given his history against Adesanya in kickboxing.
