UFC Vegas 101: Dern Vs. Ribas 2

Mackenzie Dern (14-5) is the No. 6 fighter in the official UFC strawweight rankings. A member of the UFC roster since 2018, the 31-year-old Dern is an accomplished grappler, with multiple world titles to her name in the world of Brazilian jiu-jitsu.

Dern has had an up-and-down run with the UFC over the past four years. She opened her UFC career with a 5-1 record, with her sole loss being a 2019 decision setback to Ribas. Since then, Dern has gone 4-4 with the promotion. She has not won back-to-back fights since 2020-21.

Dern ended a two-fight losing skid in August when she scored a decision win over Loopy Godinez.

Amanda Ribas (13-5) is the No. 8 fighter in the women’s 115-pound division. She is also ranked No. 10 at 125 pounds.

Ribas signed with the UFC in 2017, but her promotional debut was delayed following a positive drug test. Ribas was initially given a two-year suspension when her sample came back positive for ostarine. That suspension was terminated in early May 2019, when it was determined that the positive test came from a contaminated supplement. Ribas made her UFC debut in June 2019 with a submission win over Emily Whitmire.

Ribas went 4-0 with the UFC between June 2019 and July 2020 with two submissions and two decision wins. Since then, the 31-year-old has alternated wins and losses, accumulating a 3-4 record while fighting at 115 and 125 pounds.

Ribas’ most recent outing was a March 2024 decision loss to former two-time UFC strawweight champion Rose Namajunas at 125 pounds.
