Ateba Gautier extended his unbeaten UFC streak to five earlier tonight (Sat., May 9, 2026) at UFC 328 LIVE on Paramount+ from inside Prudential Center in Newark, New Jersey, as the hulking middleweight prospect put a violent stop to Osman Diaz courtesy of a second-round knockout punch.
This fight may have went a little further than expected, but that’s because Gautier took his time in the first round. The undefeated middleweight prospect had a lot of hype coming into this weekend and was a massive -1400 betting favorite to take care of business and send Diaz packing. It would make sense for Gautier to slow things down in the early going so he doesn’t make a mistake against Diaz, who came into UFC 328 with a 1-1 Octagon record.
massive counter right hand crumbled Diaz and as Gautier tried to rush in for ground-and-pound the referee was already there to break up the fight. It may been a tad premature, but the stoppage only prevented Diaz from suffering any unnecesary punishment.
