​“Sandman” is bummed.Former Ultimate Fighting Championship (UFC) Bantamweight title challenger Cory Sandhagen suffered a unanimous decision loss in his rematch against Mario Bautista in the “Featured Fight” on the UFC 329 main card this past weekend (Sat., July 11, 2026) inside T-Mobile Arena in Las Vegas, Nevada.AdvertisementAdvertisementAdvertisementTwo days after the loss, Sandhagen took to social media to address the defeat and reveal that he may have suffered a serious injury during the fight.“Frickin bummer man,” Sandhagen wrote. “Losing in fighting is the most embarrassing thing ever. Sucks.“Pretty sure the knee bar tore my hamstring in the first — getting MRI this week,” Sandhagen continued. “It kept locking out weird if I did certain things. So that kind of messed up my game plan.“Congrats to Mario. He was well prepared. First was close but he won it with that knee bar. Second, I won — surprisingly cause leg was jacked. Third, I wanted to have the same round as before but got dropped. Gotta fight near perfect to win at the top. Something I need to get better at.“Appreciate the love from you guys. Enjoy your week. Love you. Peace.”Sandhagen (18-7) is now riding a two-fight losing streak for the second time in his UFC career. Prior to his UFC 329 loss, “Sandman” dropped a unanimous decision title fight to Merab Dvalishvili at UFC 320 last year.The 34-year-old is now 4-3 across his last seven fights and, at least for the time being, is nowhere near another Bantamweight title shot.He also may have lost his chance to finally collide with Sean O’Malley, which has long been one of the most fun fantasy matchups in the division.AdvertisementAdvertisementAdvertisementAnd the potential injury only makes things worse.If Sandhagen did tear his hamstring (like this), the severity of the tear will determine how long he is sidelined. But if it is significant, a six-to-12-month layoff is not out of the question.In other words, Sandhagen’s rough night at UFC 329 may follow him well into 2027.Bummer, indeed.For more UFC 329 results, coverage and highlights click HERE.
