Carlos Ulberg stunned Jiri Prochazka with a first-round knockout in the main event of UFC 327 to capture the light heavyweight championship. Ulberg set up the finish by drawing Prochazka in before landing the decisive blow. The knockout came at 3:45 of the opening round. The victory is particularly remarkable given that Ulberg appeared to suffer a knee injury early in the fight. Despite the compromised mobility, Ulberg remained composed and found the perfect opportunity to finish the former champion. The result crowns a new light heavyweight king and represents a dramatic upset in the 205-pound division.
