Former UFC lightweight Melvin Guillard has not secured a victory in over 11 years. During his prime, the seasoned fighter, known as the “Young Assassin,” earned five consecutive wins in one of the most competitive divisions in the Premier Promotion. Guillard has faced notable fighters including Nate Diaz, Donald “Cowboy” Cerrone, Justin Gaethje, and two-time UFC middleweight champion Israel Adesanya, but unfortunately lost to all of them.
Recently, at 42 years old, Guillard suffered his 11th straight defeat. After his 10th consecutive loss—a first-round submission to Josiah Harrell in May—fans urged him to retire, but Guillard chose to continue fighting. His latest bout was a last-minute matchup against undefeated welterweight prospect Isaac Moreno at Fury FC 106 in New Orleans. This fight was dominated by Moreno, who secured a second-round TKO via ground and pound, extending Guillard’s losing streak to 11 and marking his second loss in 2025.
Moreno, at 27, seems to have a promising future with a 7-0 record and four finishes, including a victory over a well-known name. Meanwhile, Tony Ferguson, a former UFC interim lightweight champion who once held an impressive 12-fight winning streak against top contenders, is also struggling with an eight-fight losing streak—the longest in UFC history. At 41, Ferguson now prepares for his professional boxing debut against social media influencer Salt Papi next month.
Fan Take: This sign of lingering career struggles from former UFC stalwarts like Guillard and Ferguson highlights the brutal, competitive nature of MMA, reminding fans that even the greatest fighters face tough declines. It also signals the rise of new talents like Isaac Moreno, representing the future of the sport and the inevitable generational shift in MMA.
