McGregor's inability to begin the second round qualified the result as a Dustin Poirier TKO in the first round, cashing proposition bets in the neighborhood of 9-1 odds. That also means the fight went under 1.5 rounds (first 7:30 of the clock).
"Initially, maybe for about 30 seconds or so, a lot of guests were unsure, but then they realized the ruling of the unusual situation. It was also mentioned on the broadcast," Stations Casino sportsbook director Chuck Esposito told ESPN. McGregor closed as an underdog (+110) for just the third time in his UFC career, losing in each of the past two situations.
"Late in the week, we were high on Poirier. But then from Thursday on, it was fairly one-sided in favor of Conor. We also had some huge bets come in on the over and parlays tied to the over," Esposito said.
After McGregor closed as a -333 favorite in January's second fight, the trilogy bout opened as a pick 'em, but respected sharp wagers moved the odds in favor of Poirier. Those odds essentially did not move throughout fight week, even though the public backed McGregor like it usually does. However, perhaps with the pandemic limiting international travel, the Ireland native only received a modest ratio of wagers rather than the typical onslaught.
Poirier's victory ended an unusual night for the UFC, which often captivates fans with upsets. However, favorites went 11-1 on Saturday night (or 10-2, depending on the sportsbook). The lone upset came in the co-main event with Gilbert Burns (+140) winning a decision over Stephen Thompson.
