Conor McGregor’s Return Rumor Has Brazil Shook — And Caio Borralho Didn’t See It Coming

Conor McGregor hasn’t thrown a punch in nearly five years, and yet somehow, he still breaks the internet without lifting a finger. Go and ask Caio Borralho about it. A single cryptic post on X sent the MMA world into a frenzy, and now everyone from São Paulo to Dublin is talking about one name: Carlos Prates.

What McGregor Actually Said

Back in February 2026, McGregor took to X and dropped a vague but unmistakably pointed message about accepting a fight against a “no name.” Classic McGregor. No specifics, no confirmation, just enough to light the match and walk away.

The internet did the rest. Within hours, fans had zeroed in on Carlos Prates, the Brazilian welterweight sitting at number five in the divisional rankings. The guy hits like a freight train, fights out of the celebrated Fighting Nerds camp, and has been quietly putting the welterweight division on notice for the better part of two years. No official announcement. No UFC presser. Just vibes, speculation, and a whole lot of strong opinions.

Borralho Wasn’t in the Loop

Here’s where it gets genuinely interesting. Caio Borralho — Prates’ teammate and a rising star in his own right — admitted publicly that he had zero heads-up about the rumor. None. He found out the same way everyone else did.

But once he processed it? Borralho didn’t hesitate. He made it clear he thinks Prates would be a serious problem for McGregor. Not a feel-good underdog story. A real, legitimate threat. That kind of teammate endorsement carries weight. Borralho isn’t out here doing promotional fluff. He trains with Prates every day. He knows exactly what that man is capable of inside the octagon.

The Case For and Against This Fight

Let’s be real — there’s a reason people are divided on this. McGregor hasn’t competed since UFC 264 in July 2021, when Dustin Poirier snapped his leg in the first round. That’s a brutal image that hasn’t faded. Coming back is already a massive ask. Coming back against a knockout artist who’s actively climbing the rankings? That’s either the boldest move of his career or a serious miscalculation.

Brazilian analysts are split right down the middle. Half of them think McGregor would never put his legacy on the line against someone with this kind of danger attached to their name. The other half think that’s exactly the kind of fight McGregor gravitates toward — the ones nobody expects him to take. And honestly? Both camps make a fair point.

What’s at Stake

For McGregor, this isn’t just about winning a fight. It’s about answering a question that’s been hanging over him for years: can he still compete at the top level? A win over a live, ranked welterweight like Prates doesn’t just answer that — it screams it. A loss, though, is a different conversation entirely.

For Prates, the math is almost entirely in his favor. He gets linked to the biggest name in MMA history, gets global eyeballs on his next performance, and if he wins? He goes from cult favorite in Brazil to worldwide phenomenon overnight. There’s very little downside for him here. For the UFC, the draw is obvious, even if the casuals might scratch their heads at the matchup. McGregor sells. Full stop.
