Former two-division UFC champion Jon Jones appears to be reconsidering his retirement from mixed martial arts just 13 days after stepping away from the sport. The 37-year-old fighter recently confirmed through social media that he has re-entered the UFC testing pool, sparking speculation about a potential comeback.
Jones’ initial retirement was announced by UFC CEO Dana White, who declared that Jones had officially ended his fighting career and that Tom Aspinall would be promoted to undisputed heavyweight champion status.
