However, since then, he has rebounded with back-to-back victories over Marvin Vettori and now de Ridder.The Louisiana native has long been viewed as a talented fighter still finding consistency, but his recent performances suggest he is finally putting everything together and establishing himself among the division’s elite.Before the event, de Ridder had been vocal about his belief that his grappling could counter Chimaev’s wrestling. Having shared training sessions years earlier, he claimed to understand Chimaev’s tendencies and saw stylistic openings that could tilt the balance in his favor.His recent wins, particularly the one over Robert Whittaker, had only strengthened that narrative. Instead, the night belonged to Allen, who capitalized on his durability and pressure to wear de Ridder down. With this win, he improved his UFC record to 14-4, and 26-7 overall.
