Former champion Jon Jones is set to return to the octagon for the first time in

more than 3 years at UFC 285 in March, but talk about who will be standing across from him has been widespread.

UFC are trying to make his long-awaited heavyweight debut on March 4 at the UFC's pay-per-view event.

With divisional champion Francis  at a contractual crossroads with

the promotion, it's unclear who Jon Jones (26-1 MMA, 20-1 UFC) will face.

If Ngannou (17-3 MMA, 12-2 UFC) leaves the UFC, several names are in the mix,

but the situation remains ambiguous for the time being.
