**Constantin Ursu’s undefeated 15-0 record and recent British/Commonwealth title wins give him clear advantages in experience and power, yet Ben Vaughan’s 12-2 ledger, southpaw stance matching Ursu’s, and proven willingness to press forward create the competitive balance reflected in near-even trader pricing.** Vaughan’s two narrow majority-decision losses came against established champions, and his aggressive style could test Ursu, who is recovering from a bicep injury sustained in his last outing. Both fighters bring comparable welterweight rounds under their belts heading into the 12-round O2 Arena clash, with Vaughan motivated to capitalize on any ring rust or conditioning questions for the champion. Late updates on Ursu’s injury status, final weigh-in measurements, or camp reports remain the primary variables that could shift implied probabilities in either direction.
