RESULTS UFC BJJ 13: Tackett, Fonacier win vacant titles; Rocha armbar over Antunes disputed

The two vacant belts at UFC BJJ 13 found owners quickly, and the night's most argued moment came from the opening round of a flyweight match. Jasmine Rocha was credited with an armbar on Karen Antunes after 38 seconds. Antunes said at once that her hand movement was a slap, not a tap. Referee Chris Brennan did not reverse the stoppage, and UFC's recap says the replay supported it.

At the top of the card, William Tackett needed 86 seconds to take the middleweight title Ronaldo Junior left behind. Jay Rodriguez opened with a double-leg takedown, but Tackett got back to his feet, took the back and finished the rear-naked choke. Tackett had lost his first title try by unanimous decision, then rebuilt his case with two heel-hook finishes over Manuel Ribamar and Fedor Nikolov. Rodriguez had lost to him at both the 2023 and 2024 ADCC Trials, and before the fight said he had grown since then. Tackett's win also made him and his brother Andrew, the welterweight champion, the first brothers to hold UFC BJJ belts at the same time.

Jalen Fonacier took the bantamweight belt Mikey Musumeci gave up, and it took all three rounds. He kept hunting leg locks and took the back with a body triangle. Kleber Barboza, making his promotional debut after winning four matches at the UFC BJJ Opens, survived and countered, but all three judges sided with Fonacier. Barboza had beaten him twice in three earlier IBJJF meetings, a record that did not carry over.

Nick Rodriguez submitted Nata Tenca with a head-and-arm choke at 3:07 of round three. Referee Jason Herzog took a point from Tenca for stalling shortly before the finish. Rodriguez came in off a split draw with light heavyweight champion Mason Fowler and still wants that rematch, but none is booked.

Ffion Davies opened the main action with a head-and-arm choke on Jaine Fragoso at 2:07 of round one. She wants another shot at Cassia Moura, who beat her by split decision for the inaugural belt, but no rematch has been announced.

Watch next for who gets the first shots at the new champions, and for whether UFC BJJ names a winner of the new Submission of the Night bonus. Its announcement gave no payout or judging method.
