Introduction
UFC 259: Blachowicz vs. Adesanya took place on Saturday, March 6, 2021 at the UFC APEX in Las Vegas. It remains the only numbered UFC pay-per-view in promotion history to feature three world title fights on the same card, the most loaded card of 2021, and one of the most historically significant nights in modern UFC. The card produced an estimated 800,000 pay-per-view buys.
The main event was a two-division superfight. Israel Adesanya — the undefeated middleweight champion fresh off his UFC 253 demolition of Paulo Costa — moved up two divisions to challenge Jan Blachowicz for the light-heavyweight title. Blachowicz, the Polish underdog who had won the title by TKO'ing Dominick Reyes at UFC 253, weathered Adesanya's striking, scored two takedowns in the championship rounds, and won by unanimous decision (49-46, 49-45, 49-45). It was the first loss of Adesanya's professional MMA career.
The bantamweight title fight was the most controversial title change in UFC history. Aljamain Sterling claimed the bantamweight title from Petr Yan via DQ at 4:29 of round four — after Yan, who was clearly winning the fight, threw an illegal knee to a grounded Sterling. It was the first UFC championship change by disqualification in promotion history. The women's featherweight title fight saw Amanda Nunes defend her strap by submission — a first-round armbar of Megan Anderson at 2:03.

The Build-Up
Israel Adesanya entered 20-0 in his MMA career and was coming off the most dominant performance of his championship reign at UFC 253. The move up to light heavyweight was framed as a chance to make history. He weighed in at 200.5 lbs for the fight; Blachowicz weighed in at 205. The two-and-a-half-pound differential at the championship level was significant.
Jan Blachowicz, 38, had won the vacant light-heavyweight title at UFC 253 in September 2020 by TKO'ing Dominick Reyes. He was the +180 underdog — the largest favourite Adesanya had faced as a UFC challenger.
The bantamweight title fight saw Petr Yan, who had won the title by fifth-round TKO of Jose Aldo at UFC 251, defending against Aljamain Sterling. The women's featherweight title fight saw Amanda Nunes defending against Megan Anderson, a 6-foot Australian challenger.
Main Event: Blachowicz vs. Adesanya
Through three rounds, the fight was close. Adesanya controlled distance with the kicking game he had perfected at middleweight. Blachowicz absorbed the offence, kept walking forward, and started planting his back foot to threaten the takedown. By the end of round three, neither man had landed a fight-changing shot.
Round four changed everything. Blachowicz scored a takedown at 1:25 of the round and held Adesanya down for over three minutes. The challenger had no answer for the size and strength differential on the canvas. The judges scored the round 10-8 for Blachowicz.
Round five was a mirror. Blachowicz scored a second takedown and rode out the round on top. The final scorecards: 49-46, 49-45, 49-45 for Blachowicz. The Pole had successfully defended the light-heavyweight title; Adesanya had taken the first MMA loss of his career.
In his post-fight interview, Adesanya was gracious: "I came up here to challenge myself. I didn't get it done. I take my hat off to Jan." Blachowicz simply held up the belt: "Legendary Polish power. I told you." Adesanya would return to middleweight after the loss; his next fight (UFC 263, June 2021) was a successful third defense of the middleweight title against Marvin Vettori. He would not move up to 205 again.
Bantamweight Title: Yan vs. Sterling
Through three rounds, Petr Yan was winning. He had outboxed Aljamain Sterling in the striking exchanges, defended the takedown attempts, and built a 30-26 lead across the scorecards. Sterling had been dropped twice and was visibly hurt.
At 4:29 of round four, Sterling was on his hands and knees against the cage, recovering from a body shot. Yan stepped forward, switched his stance, and threw a flying knee directly to Sterling's head. The strike was illegal: under the Unified Rules, knees to a grounded opponent are prohibited. Sterling fell forward, holding his head, clearly unable to continue.
Referee Mark Smith called the time. After medical examination, Sterling was deemed unable to continue. The DQ was awarded; Sterling claimed the title via DQ in 4:29 of round four. It was the first UFC championship change by disqualification in promotion history.
The aftermath was immediate. Sterling was carried out of the cage on a stretcher. Yan apologised but maintained the knee had been a mistake. The two would rematch at UFC 273 in April 2022, with Sterling winning by split decision. They met a third time at UFC 280 in October 2022; Sterling won by submission. Final ledger: 2-1 Sterling (1-0 by DQ, 1-0 by SD, 1-0 by submission).

Legacy & Impact
UFC 259 is remembered as the most historically dense UFC card of the modern era. Three world titles defended on a single card; the first MMA loss of Israel Adesanya's career; the first UFC championship change by DQ; the simultaneous double-title defense of Amanda Nunes. Few PPVs have packed as many promotion-defining moments into a single broadcast.
For Adesanya, the loss did not derail his middleweight reign. He returned to 185 lbs three months later (UFC 263, June 2021), defended the title against Marvin Vettori, and went on to four more middleweight defenses before losing to Alex Pereira at UFC 281 in November 2022.
Jan Blachowicz lost the title to Glover Teixeira at UFC 267 in October 2021 (second-round submission). Aljamain Sterling held the bantamweight title for nearly two years, defending against Yan (UFC 273), T.J. Dillashaw (UFC 280), and Henry Cejudo (UFC 288) before losing to Sean O'Malley at UFC 292 in August 2023.
FAQ
How many title fights were on UFC 259?
Three. The light-heavyweight title (Blachowicz vs. Adesanya), the bantamweight title (Yan vs. Sterling), and the women's featherweight title (Nunes vs. Anderson). UFC 259 is the only numbered UFC pay-per-view in promotion history to feature three world title fights on the same card.
How did Adesanya lose his unbeaten record?
Jan Blachowicz scored two takedowns in rounds four and five and held Adesanya on the canvas for over six minutes total — a size and strength differential the Nigerian could not overcome. The final scorecards (49-46, 49-45, 49-45) reflected dominant championship rounds for Blachowicz.
Was the Yan illegal knee intentional?
Yan maintained it was a mistake — he claimed he believed Sterling had risen to a standing position. The Nevada Athletic Commission reviewed the footage and confirmed the strike was illegal under the Unified Rules. Sterling was unable to continue; the referee awarded the DQ. Yan has remained adamant it was a referee-judgement error on his part, not a deliberate foul.
Did Adesanya try to win the light-heavyweight title again?
No. Adesanya returned to middleweight after UFC 259 and never moved back up to 205. The loss to Blachowicz convinced him that his physical frame was built for middleweight.
Did Yan and Sterling fight again?
Yes — twice. They rematched at UFC 273 in April 2022, where Sterling won by split decision. They fought a third time at UFC 280 in October 2022; Sterling won by second-round rear-naked choke submission. Final ledger: 3-0 Sterling (1 DQ, 1 SD, 1 SUB), though the first two results remain contested.
How does UFC 259 compare to UFC 258?
UFC 259 drew approximately 800,000 PPV buys versus UFC 258 (600,000) three weeks earlier. The 200,000 jump reflected the three-title-fight format and the magnetism of Israel Adesanya's two-division-title pursuit.
