Irish MMA star Conor McGregor is preparing to return to the UFC after a long hiatus stemming from physical fatigue and a loss of motivation, Azernews reports.

Conor McGregor is officially back and undergoing drug tests ahead of a potential comeback. According to the official UFC Anti-Doping website, as of Aug. 1, McGregor has registered his first test session of 2025.

After the scrap with one-time Bellator star Chandler was called off, it seemed as though McGregor would never make a return to the Octagon as he was occupied by his other business interests outside of the UFC, and a recent lengthy legal case in his native Ireland.
