The UFC 319 lineup has undergone a slight shake-up just a couple of weeks out from fight night.

According to a recent report from Ag. Fight, JJ Aldrich has withdrawn from her scheduled women’s flyweight bout against Karine Silva due to undisclosed issues. Stepping in on short notice, Dione Barbosa will now face Silva at UFC 319.

Silva was last in action at UFC 309 this past November, where she suffered her first promotional loss via unanimous decision to Viviane Araujo. The 31-year-old Brazilian earned her UFC contract with a second-round submission victory over Yan Qihui on Dana White’s Contender Series in October 2021.

"Killer" has secured four wins in five UFC outings, with three coming by submission against the likes of Ketlen Souza and Maryna Moroz. She holds a professional record of 18-5, with an impressive 17 of those victories earned via stoppage.

Meanwhile, Barbosa most recently competed at UFC Vegas 105 this past April, where she secured a first-round submission win over Diana Belbita, bouncing back from a unanimous decision loss to Miranda Maverick in July 2024.

"The Witch" punched her ticket to the UFC with a submission win over Rainn Guerrero on DWCS in September 2023. The former Olympic judoka holds a professional MMA record of 8-3, with four of those victories coming by submission.

Interestingly, UFC 319 won’t be the first time Silva and Barbosa share the cage. The pair previously met in May 2019 at Katana Fight 9, where "The Witch" claimed a unanimous decision victory.
