Jose Aldo Has One Piece of Advice for Conor McGregor: Drop to 155

Ten years after Conor McGregor knocked him out in 13 seconds to take the undisputed featherweight belt, Jose Aldo has some unsolicited career advice for the Irishman: forget welterweight and come back at 155. Speaking to reporters, the Brazilian argued McGregor still carries the frame for lightweight and that the division is open enough right now for him to walk in and snatch a title.

The context is grim. McGregor (22-7, 19 KO) finally returned in July after a five-year layoff to rematch Max Holloway, then blew out his knee seconds into the fight while attempting a jumping kick. He underwent surgery in August and has said he's confident about the recovery, but a 2027 return is still just a target — no bout agreement is signed.

Why Aldo Says 155

Aldo's logic is about opportunity, not sentiment. He pointed to Ilia Topuria vacating and moving up, then noted the shuffling at the top has left things messy — his read is that a returning McGregor could beat a mid-tier name and suddenly be back in the title conversation. It's a spicy take, but not a crazy one given how much the lightweight picture has turned over.

There's a catch, and Aldo named it: the weight. He suggested McGregor would need serious dietary re-education to get back down and stay lighter, because the Irishman has packed on muscle and mass in recent years. McGregor's own coach John Kavanagh has said 170 is now a comfortable cut and that it'd take something big to justify shedding the extra 15 pounds for a UFC bout.

The Sympathy Behind the Advice

For two men who fought the ugly end of one of the UFC's great rivalries, there's no venom here. Aldo called the injury sad — the buildup, the fight week, millions tuning in, and then it ends on a busted knee. He said he always roots for fighters to come back and do their job, and he hopes McGregor recovers physically and mentally.

The bigger worry Aldo raised is the one nobody can answer yet: what version of McGregor comes back. Between the long layoff and now another extended stint on the shelf, Aldo openly wondered whether the 37-year-old returns anywhere near his prime. The frame is still there for 155. Whether the rest of him is remains the whole question.
