The sequence that led to the finish started after both fighters ducked their heads down going into an exchange of strikes and they clashed heads in a violent manner. Unfortunately it was Holland who got the worst of it after he was nearly knocked out from the accidental headbutt, which sent him crashing to the canvas.
Referee Dan Miragliotta nearly stepped into stop the contest but instead he let the action continue with Daukaus seizing the moment by pouring on the punishment and then eventually wrapping up a standing rear-naked choke submission against the cage.
Once it was clear there was no escape, Holland tapped out and it appeared for a moment that Daukaus was going to get the biggest win of his young UFC career.
As soon as the fight ended, Miragliotta started conversing with the other ringside officials about a replay that clearly showed the clash of heads, which then led to the finish from Daukaus. While Miragliotta acknowledged that he saw the accidental foul, he allowed the fight to continue because he said he saw Holland start to fight back.
After a long discussion, the decision was ultimately made the declare the fight a no contest since the submission came after Holland was obviously compromised by the clash of heads.
The fighters shook hands in the cage with Holland and Daukaus both promising to run it back at some point in the future following a disappointing end to the co-main event in Las Vegas.
