Song Yadong produced the biggest win of his UFC career at home, stopping former title challenger Umar Nurmagomedov with a right uppercut at 1:48 of Round 2 in the UFC Shanghai main event. The result was a major upset: reports listed Song as a roughly 5-to-1 underdog, while Umar entered the bout ranked No. 2 in the bantamweight division.

The finish earned Song a $100,000 Performance of the Night bonus and immediately moved him into the 135-pound title picture. But the moments after the stoppage created a separate controversy involving Umar’s brother, Usman Nurmagomedov.

How Song Yadong stopped Umar Nurmagomedov
Song spent the opening round dealing with Umar’s grappling threat and appeared to narrowly lose the frame on at least one unofficial scorecard. Early in Round 2, Umar again looked to close distance for a takedown. Song stuffed the attempt and timed a short right uppercut as Umar dipped forward.

The punch landed near Umar’s ear and was followed by additional shots before referee Marc Goddard stopped the contest. The official result was Song Yadong def. Umar Nurmagomedov by knockout at 1:48 of Round 2.

For Umar, the loss was the second of his professional career. For Song, it was a statement victory over a highly regarded contender and, according to contemporaneous reports, his first knockout win in the UFC.

Why Usman Nurmagomedov’s cage entrance caused backlash
Usman, who was part of Umar’s corner, immediately vaulted into the Octagon after the stoppage. The apparent aim was to reach his unconscious brother, but the timing put him in Song’s path while the Chinese fighter was celebrating. Corner personnel are not permitted to enter the cage at that point before the appropriate post-fight medical process, a concern also noted by Daniel Cormier.

Video appeared to show Usman pushing Song away and then beginning a backward or spinning-elbow motion before pulling it back. No elbow connected, and the brief confrontation did not develop into a sustained brawl.

That distinction matters. The footage supports a collision, a shove and an apparent striking motion, but it does not establish Usman’s intent. Some viewers interpreted the movement as an attempted attack, while others saw a reflexive reaction as the two men crossed paths. Available reporting did not identify a confirmed UFC or athletic-commission sanction.

Usman’s denial and Cormier’s defense
Usman rejected the accusation that he intended to hit Song. In a statement after the event, he said, “If I had wanted to, I would have hit him,” while also telling critics to calm down.

Cormier offered a different reading of the same footage. He said Song was running toward Usman, who reacted by reaching out to prevent a collision, and argued that Usman did not elbow or attack Song. Cormier still acknowledged that Usman was not supposed to enter the Octagon before being cleared to do so.

The public response was more severe. Fans and some members of the MMA community called for disciplinary action, the loss of Usman’s corner credentials or a reconsideration of any future UFC opportunity. Those demands were reactions to the footage—not evidence of a confirmed ruling.

The aftermath was not an extended brawl
The chaotic moment was followed by a more respectful exchange. Khabib Nurmagomedov was reported to have helped tend to blood around Song’s eye after the knockout, and Song praised the Nurmagomedov team after the fight.

Reports also said Umar indicated that he was fine and intended to return. The available material does not provide a detailed medical assessment, so the safest conclusion is limited: Umar’s camp presented the loss as something he planned to move past, not the end of his career.
Does Song deserve the next title shot?
Song made his position clear after the victory: he wants the winner of Petr Yan versus Merab Dvalishvili. His knockout of Umar gives that request a strong sporting argument, especially because it came against a highly ranked former title challenger and ended the fight decisively.

The title path is not automatic, however. Song had already lost a unanimous decision to Sean O’Malley at UFC 324 in January, and O’Malley remained part of the title conversation after that win. Reporting also identified the Yan–Dvalishvili result as a key factor in determining the division’s next matchup.

That leaves the UFC with a genuine matchmaking choice rather than a settled answer. Song’s Shanghai performance is arguably the strongest case for his next title opportunity, but the promotion may still weigh O’Malley’s prior win, the outcome of Yan–Dvalishvili and the commercial value of each potential matchup.

For now, the clearest takeaway is simple: Song turned a homecoming main event into a career-defining upset, while the Usman incident added controversy without changing the official result. The knockout—not the near-collision—was the event that transformed Song from contender into a credible title challenger.
