As the fight was waved off Saturday night with McGregor injured on the canvas, young Rush Holloway shouted taunts from cageside that quickly spread across social media, turning an already chaotic main event into one of the weekend's biggest storylines.The moment capped a fight that had been building for 13 years, ever since McGregor and Holloway first met in 2013. This time, Holloway needed just over a minute to settle the rematch.Max Holloway's son Rush drops brutal jab at Conor McGregorRush has been a familiar face at his father's fights for years, and he wasted no time reacting once McGregor went down. "Who's your daddy? Who's your daddy now?" Rush shouted from cageside as referee Mike Beltran stopped the contest. The line was a direct callback to McGregor's own pre-fight trash talk, in which the Irishman claimed he had "sonned" Holloway in their first meeting and repeatedly referred to himself as Holloway's daddy in the build-up to the rematch.McGregor left the Octagon under his own power but was visibly limping, exiting the arena before he had even changed out of his fight gear.Fans are fumed over Rush Holloway's remark on Conor McGregorConor McGregor, right, embraces Max Holloway after McGregor lost in a welterweight fight at the UFC 329 mixed martial arts event Saturday, July 11, 2026, in Las Vegas. (AP Photo/John Locher)The clip of Rush's taunt divided fans online. Some found it endearing, while others felt it was premature given how the fight actually ended. One fan, @elcompa7jr, wrote bluntly, "Your dadddy didn't do anything." Another, @thepoipoundah, pushed back on the criticism, defending the moment as nothing more than a son supporting his father. Several commenters, including @levipdx_, noted that the win came by injury rather than a finish, arguing there was little to celebrate beyond the result on the scorecard.“Young man, you have a long road to humble,” one fan shared.Conor McGregor's return ends with disappointing defeatMcGregor's fight lasted only 69 seconds. He opened with a flying kick, landed awkwardly on his right knee and never recovered, falling to the canvas multiple times before Beltran halted the action. UFC president Dana White said doctors suspected a torn ACL and noted there were no signs of injury at Friday's weigh-in.Following the fight, McGregor took to X to break his silence over the defeat. “My head gasket is gone. Destroyed. I had no injury/injuries going into the fight. I was throwing kicks, planted and jumping, all throughout camp as well as backstage before the fight. This came out of nowhere. I am beyond dark here. I can only describe it as hell,” he wrote on X.It was McGregor's first fight since 2021, when a broken leg against Dustin Poirier ended his previous run. His comeback had been delayed repeatedly since, including a scrapped 2024 bout with Michael Chandler and a civil finding in Ireland that he was liable for sexual assault. Holloway, for his part, showed sportsmanship in victory, telling the booing crowd that McGregor was "an absolute animal" for continuing to ask to fight on despite the injury. McGregor later posted that the injury "came out of nowhere," adding that he had shown no signs of trouble in fight camp.With Holloway and McGregor now split 1-1 across their rivalry, a trilogy fight remains on the table, though McGregor's recovery timeline and the UFC's appetite for a third meeting remain open questions.
