The UFC is set to return to London, England on March 22 next year for a Fight Night event at the O2 Arena.
Two top 15 match-ups have now been made official for the card with veterans taking on rising contenders in their divisions.
At light heavyweight, former champion Jan Błachowicz makes his return to the Octagon having not fought since his loss to Alex Pereira at UFC 291 in 2023.
"Polish Power" will be out to defend his #4 spot in the rankings against the surging Carlos Ulberg.
The City Kickboxing fighter and former kickboxer has won seven in a row since losing his UFC debut to Kennedy Nzechukwu back in 2021.
"Black Jag" recently defeated former title challenger Volkan Oezdemir last month and on this current winning streak, he has produced four first-round knockouts.
The second fight that has been made official by the UFC takes place in the heavyweight division as England's Mick Parkin earns his first big outing in the rankings.
A four-fight win streak, with a performance bonus last time out at UFC 304 where he produced his first finish inside the Octagon, has earned the 29-year old the #14 spot.
He will now face a man that his training partner, Tom Aspinall, has also faced and defeated in London.
Poland's Marcin Tybura is coming off of a win over Jhonata Diniz at UFC 309 last month and with prior victories over the likes of Tai Tuivasa, Serghei Spivac and Blagoy Ivanov, he will be the toughest test of Parkin's undefeated career to date.
More fights are sure to be announced in the coming weeks including the main event which former welterweight champion Leon Edwards recently stated he will be one half of.
