Mackenzie Dern is a Brazilian Jiu-Jitsu black belt and a mixed martial artist who currently competes in the strawweight division of the Ultimate Fighting Championship (UFC). She made her professional MMA debut in 2016 after a successful grappling career, which included multiple world championship titles and a bronze medal at the ADCC Submission Wrestling World Championship.
Dern quickly made a name for herself in the MMA world, winning her first four fights in the first round, all via submission. However, she suffered her first MMA loss in 2018 against Amanda Ribas and another loss in 2019 against Amanda Nunes's training partner, Amanda Cooper. She bounced back with three consecutive victories against Hannah Cifers, Randa Markos, and Nina Nunes, earning her a spot in the UFC's top 10 rankings.
Amanda Lemos is another Brazilian MMA fighter who competes in the UFC's women's strawweight division. She has a record of 10 wins and one loss, with her sole defeat coming in her UFC debut against Leslie Smith. Since then, Lemos has won four consecutive fights, including two by knockout.
Zhang Weili, on the other hand, is the current UFC strawweight champion. She won the title in 2019 with a stunning first-round knockout of Jessica Andrade and successfully defended it against Joanna Jedrzejczyk in a five-round war. Zhang is known for her aggressive striking, excellent takedown defense, and relentless pace.
In summary, the news mentioned in the question is a prediction that Mackenzie Dern believes Amanda Lemos will knock out Zhang Weili at UFC 292. However, it is important to note that predicting the outcome of a fight is always a risky proposition, as anything can happen in the Octagon. All the fighters involved in this event are talented and accomplished athletes who have worked hard to reach the top of their respective divisions. Fans of MMA will undoubtedly be looking forward to this matchup and hoping for a great fight.
