“He’s Too Small”: Carlos Ulberg Warns Khamzat Chimaev to Stay in His Lane at Middleweight

UFC middleweight champion Khamzat Chimaev has been openly discussing a move to light heavyweight, but top‑ranked 205‑pounder Carlos Ulberg has hit back with a blunt warning: stay at 185 and leave 205 alone. In a recent interview with Combat Sports Network, Ulberg told Chimaev he is “too small” for the light‑heavyweight division and drew a clear line between their weight classes.

Khamzat Chimaev’s Move Up Sparks Backlash: Carlos Ulberg Says 205 Is His Division

Ulberg’s message came amid growing speculation that Chimaev intends to vacate or briefly defend his middleweight title before pursuing a second belt at 205 pounds. Chimaev has previously told ESPN that he plans just one defense of his middleweight championship before shifting to light heavyweight, with reigning 205‑champ Alex Pereira named as his preferred target. That same line of thinking has also kept UFC president Dana White on the back foot, with White insisting Chimaev must first defend the middleweight belt before any jump upward is considered. Via CSN Watch, he said:

“He’s too small. Stay in your lane, brother. Handle your business over there and I’ll handle mine here. 205 is mine!”

Within the light‑heavyweight division, Ulberg has been quietly building the kind of case that usually earns a title shot. He is currently ranked inside the top three at 205 and has a nine‑fight UFC win streak, including a first‑round knockout of veteran Dominick Reyes in the main event of UFC Perth last September. That finish pushed him firmly into the title‑picture conversation, even as the division’s immediate future remains tangled by questions around Pereira’s possible move to heavyweight.

With Pereira’s status at 205 uncertain, talk has turned to a potential title‑“vacant” bout between Ulberg and Jiri Prochazka, which would give ‘Black Jag’ a clearer path to gold. At the same time, Chimaev’s repeated hints at a 205 jump have created a different kind of pressure: if he were to claim the belt, Ulberg would suddenly be facing a wrestler with size, speed, and power that few in the division have ever matched. Ulberg has acknowledged that Chimaev’s style and takedown pressure would be a difficult matchup, even though he carries strong defensive numbers in areas like takedown defense.

Against that backdrop, Ulberg’s “stay in your lane” line reads less like casual trash talk and more like a strategic attempt to protect his own title‑shot window. By framing Chimaev as undersized for 205, he positions himself as the natural heir to the division regardless of whether Pereira stays at light heavyweight or moves up. For now, UFC brass appears to be leaning on Chimaev to defend in the middleweight bracket first, which keeps Ulberg’s path open while the real question hangs: if‑and‑when Chimaev does arrive at 205, will the division’s size and power really be enough to hold him back, or will this line be the moment Ulberg first had to draw a boundary that eventually gets erased.
