William Tackett is favored to win this BJJ grappling match against Manuel Ribamar, primarily due to a dominant prior submission victory and his current high-level training regimen with UFC BJJ.
William Tackett face Manuel Ribamar on Friday, part of the 2026 UFC BJJ season. Both fighters' recent records, methods of victory, and stylistic matchup factors are detailed alongside the prediction below.
FIGHT WINNER
William Tackett
33%
William Tackett holds a significant advantage in this matchup, having previously submitted Manuel Ribamar with a heel hook in just 75 seconds at Fight to Win 166 in March 2021. This head-to-head result is a strong indicator of Tackett's ability to finish Ribamar. Furthermore, Tackett has recently signed an exclusive deal with UFC BJJ and has been training at the UFC Performance Institute, which provides him with elite-level resources for preparation and skill development. While he recently lost a decision for the inaugural UFC BJJ middleweight title, he has been consistently competing at a high level within the UFC BJJ promotion. Manuel Ribamar is a highly accomplished black belt with numerous IBJJF titles, including a No-Gi World Championship and a Pan Championship, and a recent World Masters win in 2023. However, the decisive nature of their previous encounter, combined with Tackett's current training environment and focus, suggests a repeat performance is likely. Tackett's technical refinement, particularly in leg locks, makes a submission victory a strong possibility, likely in the early rounds given their last fight's quick finish.
