ACBJJ has added one of the lightweight grappling scene's most decorated names to its Rio de Janeiro show. Diogo Reis, a black belt from Manaus and a two-time ADCC champion, is confirmed for ACBJJ 23, but his opponent has not been announced, so his slot on the card is still open.
Reis arrives with a reputation built on fast movement, tight guard passing and strong positional control, according to Recorte da Luta. His ADCC titles came at the biggest grappling tournament in the world, which makes him a natural fit for a card already stacked with recognizable names.
At the top, the main event pairs two different eras of the sport at 100 kg. Rousimar "Toquinho" Palhares is known for his leg locks, and he faces Andre Galvao, the Atos leader and a multiple-time world champion. Our records already list Galvao as Palhares' next booked fight, which confirms this is his only scheduled appearance right now.
The co-main event is a 90 kg no-gi bout between American Kelvin Gastelum and Rodolfo Vieira. Both have spent recent years in MMA. Vieira is a jiu-jitsu world champion who fights in the UFC middleweight division, so the matchup tests two MMA-based fighters under grappling-only rules.
Watch for ACBJJ to name Reis' opponent and fill out the rest of the card before Nov. 13.
