UFC heavyweight champion Jon Jones unexpectedly retired, leaving interim champion Tom Aspinall as the new title holder. Jones' retirement concludes a lengthy and controversial standoff, following his victory over Stipe Miocic. Aspinall, having already defeated top contenders, is expected to quickly defend his newly acquired title, likely against Ciryl Gane. The situation leaves a complicated legacy for Jones while Aspinall begins his reign under less-than-ideal circumstances.
