An alarming situation unfolded at UFC Vegas 110 last night (Sat., Nov. 1, 2025) after rising Cuban Featherweight prospect Yadier del Valle shocked Isaac Dulgarian, submitting him in the first round inside the UFC Apex in Las Vegas, Nevada (watch highlights).
However, what happened before the fight is what’s causing major concern. Roughly an hour before the Featherweight bout, the betting line shifted dramatically, sparking widespread suspicion among fans and oddsmakers.
Dulgarian opened as a -240 favorite, but his line tightened to -160 just before the fight. Even more suspicious, the prop bet for a first-round finish dropped from +850 to +475 — a massive swing suggesting tens of thousands of dollars in late action. As a result, multiple sportsbooks, including DraftKings, reportedly pulled the prop line entirely (more details here).
Now, in the aftermath, two popular sportsbooks, Caesars and William Hill, have issued refunds for wagers on the Dulgarian–Del Valle fight after social media users flagged the unusual movement and accused the bout of being “fixed.”
To make matters worse, Dulgarian previously trained under James Krause, the embattled coach currently blacklisted by UFC amid a high-profile betting scandal. That said, Dulgarian has since distanced himself from Krause, relocating to Factory X in Colorado well before UFC’s ban.
It remains unclear whether the Nevada State Athletic Commission (NSAC) or UFC will launch a formal investigation, but given the circumstances — and the optics — this situation is almost certain to get uglier in the days ahead
