## Event overview
The card ran in Shanghai's local prime time, which placed the main card at 6:00 AM EDT for North American viewers, streamed on Paramount+.[1](https://www.ufc.com/event/ufc-fight-night-august-23-2025) It was the promotion's first event in Shanghai since 2017, and the UFC positioned it around Zhang, a Chinese light heavyweight prospect fighting at home.[2](https://www.sherdog.com/news/articles/Fight-Facts-UFC-Fight-Night-257-Walker-vs-Zhang-198167) • [7](https://www.ufcespanol.com/news/ufc-returns-shanghai-blockbuster-main-event-battle-ranking-light-heavyweights-johnny-walker-12) The event page listed the headliners as the #13 and #14 ranked light heavyweights, Walker and Zhang respectively.[1](https://www.ufc.com/event/ufc-fight-night-august-23-2025)
## Main event
**Walker's upset.** Walker, a 33-year-old Brazilian who had last fought in June 2024 and lost to [Volkan Oezdemir](https://www.edgepedia.org/volkan-oezdemir), opened as a +270 underdog against Zhang's -340.[1](https://www.ufc.com/event/ufc-fight-night-august-23-2025) • [8](https://www.the-independent.com/sport/ufc/johnny-walker-ufc-shanghai-zhang-mingyang-tko-b2815678.html) He opened the fight with a takedown attempt immediately after what many viewers read as a retracted glove touch; Walker later denied faking the touch, saying he had raised his hand out of habit after the pre-fight touch and simply shot for a takedown, which failed and left him pulling guard.[8](https://www.the-independent.com/sport/ufc/johnny-walker-ufc-shanghai-zhang-mingyang-tko-b2815678.html)
The finish came in the second round. Walker felled Zhang with heavy low kicks, then secured the stoppage with a prolonged barrage of strikes on the downed Chinese fighter at 2:37 of round 2.[3](https://us.ufcespanol.com/news/main-card-live-results-highlights-winner-interviews-recaps-ufc-fight-night-walker-vs-zhang-shanghai) • [1](https://www.ufc.com/event/ufc-fight-night-august-23-2025) Walker said after the fight that he believed one of the kicks had broken Zhang's leg, though that injury was unconfirmed.[8](https://www.the-independent.com/sport/ufc/johnny-walker-ufc-shanghai-zhang-mingyang-tko-b2815678.html) The win ended a run in which [Brazilians](https://www.edgepedia.org/brazilians) had gone 0-10 in 2025 UFC headliners, and it was Walker's first marquee victory of that kind in the period covered by the stat breakdown.[2](https://www.sherdog.com/news/articles/Fight-Facts-UFC-Fight-Night-257-Walker-vs-Zhang-198167)
**What it cost Zhang.** Zhang entered the night on a 12-fight winning streak, with his last four wins inside the UFC, all by stoppage: Brendson Ribeiro at [UFC 298](https://www.edgepedia.org/ufc-298) (KO, 1:41 of round 1), Ozzy Diaz (strikes, 2:25 of round 1), Anthony Smith (strikes, 4:03 of round 1), and then the Shanghai loss.[5](https://www.ufc.com/athlete/zhang-mingyang?language_content_entity=en) His UFC profile records 13 wins by KO and six by submission, with 19 first-round finishes across his career, and lists the Walker loss as the streak-ender.[5](https://www.ufc.com/athlete/zhang-mingyang?language_content_entity=en) Zhang returned five months later at [UFC Fight Night: Song vs. Figueiredo](https://www.edgepedia.org/ufc-fight-night-song-vs-figueiredo) in Macau, where Alonzo Menifield stopped him with strikes at 4:15 of the first round.[5](https://www.ufc.com/athlete/zhang-mingyang?language_content_entity=en)
## Rest of the card
**Co-main event.** Former bantamweight champion [Aljamain Sterling](https://www.edgepedia.org/aljamain-sterling) met former featherweight title challenger [Brian Ortega](https://www.edgepedia.org/brian-ortega) at a catchweight of 153 lb, with Sterling a sizable favorite over Ortega (+240).[6](https://www.sherdog.com/news/news/UFC-Shanghai-Walker-vs-Zhang-PlaybyPlay-Results-Round-Scoring-198144) • [9](https://www.sherdog.com/news/articles/Prime-Picks-UFC-Shanghai-Walker-vs-Zhang-198137) Ortega won a five-round unanimous decision.[1](https://www.ufc.com/event/ufc-fight-night-august-23-2025)
**Heavyweight bout.** [Sergei Pavlovich](https://www.edgepedia.org/sergei-pavlovich), the once-feared knockout artist, outpointed [Waldo Cortes-Acosta](https://www.edgepedia.org/waldo-cortes-acosta), who was riding a five-fight win streak, over three rounds for a unanimous decision, a result that moved Pavlovich back toward contender status while ending Cortes-Acosta's winning streak.[6](https://www.sherdog.com/news/news/UFC-Shanghai-Walker-vs-Zhang-PlaybyPlay-Results-Round-Scoring-198144) • [1](https://www.ufc.com/event/ufc-fight-night-august-23-2025) • [11](https://www.ufc.com/news/official-judges-scorecard-ufc-fight-night-walker-vs-zhang-shanghai)
**Other main card results.** Welterweight Nueraji Taiyilake stopped Kiefer Crosbie by TKO from elbows at 3:33 of round 1 in his Octagon debut, a performance that included a two-point deduction for an illegal knee to a downed opponent's head.[6](https://www.sherdog.com/news/news/UFC-Shanghai-Walker-vs-Zhang-PlaybyPlay-Results-Round-Scoring-198144) Flyweight Su Mudaerji took a unanimous decision over Kevin Borjas.[1](https://www.ufc.com/event/ufc-fight-night-august-23-2025)

## Place in the UFC's China strategy
The Shanghai card was part of a renewed push into [Greater China](https://www.edgepedia.org/greater-china). The UFC described it as its fourth event in mainland China and eighth in Greater China, held in local prime time to serve the domestic audience.[7](https://www.ufcespanol.com/news/ufc-returns-shanghai-blockbuster-main-event-battle-ranking-light-heavyweights-johnny-walker-12) The promotion later cited the sold-out Shanghai show, together with the sold-out [UFC Fight Night: Yan vs. Figueiredo](https://www.edgepedia.org/ufc-fight-night-yan-vs-figueiredo) in Macau in November 2024, as proof of demand for live UFC events in China, and announced a multi-event strategic partnership with Galaxy Macau to stage more events at the Galaxy Arena.[10](https://us.ufcespanol.com/news/ufc-and-galaxy-macau-announce-multi-event-strategic-partnership) The results in Shanghai were mixed for the home crowd: local fighters won several bouts, but the hometown headliner ended in a stoppage loss.[2](https://www.sherdog.com/news/articles/Fight-Facts-UFC-Fight-Night-257-Walker-vs-Zhang-198167)
