Jan Błachowicz’s UFC London Return Against Carlos Ulberg
Jan Błachowicz returned from a long layoff to face Carlos Ulberg on March 22, 2025, and lost a unanimous decision, with all three judges scoring it 29–28 for Ulberg.
The matchup followed Błachowicz’s split-decision loss to Pereira in July 2023. His scheduled return against Ulberg was part of the London card headlined by Leon Edwards and Sean Brady; the venue was The O2 in London.
Ulberg won the light-heavyweight co-main event after 15 minutes. The official scorecards record three 29–28 cards for Ulberg. The event results list Pereira’s earlier split-decision win over Błachowicz.
A former champion’s return
Błachowicz brought a substantial championship history to the Ulberg matchup. He won the vacant UFC light-heavyweight belt by stopping Dominick Reyes in the second round at UFC 253 in September 2020. He then defended it against middleweight champion Israel Adesanya, winning a five-round unanimous decision at UFC 259 in March 2021. The official UFC 259 recap records that successful defense.
By the time he faced Ulberg, Błachowicz had been out of competition since the Pereira bout in July 2023. Ulberg arrived with seven consecutive wins and extended that streak to eight by defeating the Polish veteran, according to the London event report.
The three matching scorecards show that the judges agreed on the overall winner in London. It was a non-title contest between a former champion returning to action and a contender continuing his rise. The result therefore belongs to the division’s contender picture, rather than a championship rematch between Błachowicz and Pereira.
