Lauren Murphy has decided it's time to walk away from the sport and a professional career that lasted over 15 years, with a loss at UFC Nashville. The 41-year-old veteran made her final appearance, going three hard rounds with rising Brazilian fighter Eduarda Moura.While it wasn’t the fairy tale ending she would've wanted, it was the kind of gritty, no-quit effort that defined Murphy’s career. Moura took the win by unanimous decision, winning all three scorecards 29-28. It was her second straight victory since dropping down to flyweight and the most high-profile win of her UFC run so far.Moura was the sharper fighter early, and her strikes were cleaner. However, she started to fade late, and that’s when Murphy surged. In the third, the American nearly caught a guillotine choke that had the crowd on its feet. Moura survived and rallied just enough to finish strong, but Murphy’s pressure made the final minutes feel like a fight between equals.After the loss, Murphy confirmed this was her last outing. She leaves behind a resume that includes a title in Invicta, 10 years on the UFC roster, and countless battles with the division’s elite.Check out the X post below:Several fans took to X to react to Murphy's retirement, writing:"Yup.
