At UFC 327 held in Miami, Florida, Carlos Ulberg claimed the vacant light-heavyweight title by defeating Jiri Prochazka in the first round, despite suffering a knee injury. Ulberg, who has now won 10 of his 11 UFC fights, faced a challenging moment when he injured his right knee after an awkward landing. However, he capitalized on an opening, delivering a stunning left hook that knocked Prochazka out. Prochazka, who was favored to win, admitted to feeling 'mercy' for Ulberg and dropped his guard, which ultimately led to his defeat. UFC president Dana White speculated that Ulberg's injury might be a torn anterior cruciate ligament (ACL), which typically requires extensive recovery time. The fight garnered significant attention, not only for the upset but also because US President Donald Trump was present at the event, while Vice-President JD Vance was engaged in unsuccessful peace talks in Pakistan. The UFC is planning a celebratory event at the White House on June 14 to mark 250 years of American independence.
