UFC legend Jon Jones announced his retirement from mixed martial arts on June 21, 2025, paving the way for Tom Aspinall to be crowned the new heavyweight champion, per ESPN. Jones, 38, made the announcement after a career spanning 17 years, citing injuries and a desire to focus on family.
Jones, with a 27-1 record, vacated the heavyweight title he won in 2023 against Ciryl Gane. His retirement follows a 2024 defense against Stipe Miocic, marred by controversy over avoiding Aspinall. Aspinall, 32, the interim champion since 2023, was elevated to undisputed champion, with a 15-3 record and 100% finish rate. The Briton, known for his knockout power, faces Curtis Blaydes next.
Jones’s exit, with 10 title defenses, ends a polarizing legacy, tainted by doping violations. Aspinall’s coronation, celebrated in posts on X, positions him to lead UFC’s heavyweight division, valued at $500 million. UFC CEO Dana White lauded both fighters.
