Thirty-eight-year-old former two-division UFC champion Jon Jones has been added again to the list of athletes subject to the league’s drug-testing program.
The update was posted on the official UFC website.
Jones last entered the octagon in November 2024 at UFC 309, defeating Stipe Miocic by TKO in the third round. In June 2025 UFC CEO Dana White announced that Jones had retired and that Tom Aspinall had become the new heavyweight champion.
Jones’s record stands at 28 wins and one loss, with one fight ruled a no contest.
