Caio Borralho leans on brains and grappling for UFC 326 co-main bout
caio borralho will meet Reinier de Ridder on Saturday, March 7, 2026, at T-Mobile Arena in Las Vegas as the Paramount+-streamed co‑main event of UFC 326, a matchup that reunites two 185‑pound contenders who both missed title opportunities in their last outings.
Caio Borralho brings jiu-jitsu, teaching chops and a chess‑player’s mindset
Caio Borralho, the 33‑year‑old Brazilian middleweight nicknamed the “King of the Nerds, ” is known for more than fight camp and conditioning inside his Sao Paulo gym, where a mural of Albert Einstein watches practice; he taught chemistry and mathematics and plays chess, and he said, “I like science, I like to study and I also like getting to know myself. ”
Borralho leads The Fighting Nerds team under head coach Pablo Sucupira, and his gym mates include Carlos Prates, Jean Silva and Mauricio Ruffy; the group has pushed into 2026 with Ruffy and Silva collecting wins, while Borralho looks to return to the win column after a loss to Nassourdine Imavov at UFC Paris last year.
How the matchup shapes up at 185 pounds
On the feet and on the mat, the co‑main event is a stylistic chess match: Reinier de Ridder is a tall, lanky 6'4" contender with 13 submission wins and a reputation for spearing knees, while caio borralho is a grappler first and a jiu‑jitsu black belt who has sharpened his striking after notable work against Jared Cannonier.
Both men arrived at UFC 326 in similar positions, having come up short in fights that might have delivered title shots — Borralho to Nassourdine Imavov and de Ridder to Brendan Allen — and previews note that de Ridder’s heavy activity and big weight cuts have taxed his gas tank, which showed in his performance versus Allen.
Keys for fight night and what’s at stake
Strategically, Borralho’s best path is to mix his top control with improved boxing and movement rather than rush forward; de Ridder will try to crash through distance, land a hard knee and use his clinch takedowns to change the pace. Analysts point to takedowns and cage control as decisive elements for a fighter like Borralho, who can avoid sweeps and submissions from de Ridder while chipping away with elbows and top pressure.
Both men have momentum to reclaim: Borralho had been flawless in the Octagon until UFC Paris, and victory in Las Vegas would put him back in contention after that first UFC defeat; de Ridder, who fights as “RDR, ” needs a strong showing to counter questions about his conditioning and recent form.
Fight night is set for Saturday, March 7, 2026, at T‑Mobile Arena in Las Vegas, Nevada, with the bout positioned as the co‑main event of UFC 326 and available on Paramount+; the winner will leave with a clearer trajectory in the middleweight landscape, while the loser will face another crossroads for 185‑pound contention.
