In MMA, a no contest is typically associated with an accidental strike that causes one competitor to become unable to continue fighting. A referee can declare a match as a no contest if both fighters violate the rules or if a fighter is unable to continue due to an injury sustained as a result of a foul.

Because there are so many ways to win (or lose) a fight, bouts in the UFC can be very exciting. In a match that is decided by … LAS VEGAS – Tim Means is pleading ignorance for the illegal knees that brought about a bizarre no-contest in Friday’s UFC 207 curtain-jerker.
Means (26-7-1 MMA, 8-4 UFC) and fellow welterweight Alex Oliveira (16-3-1 MMA, 5-2 UFC) were off to an entertaining start in the UFC Fight Pass-streamed preliminary-card bout at T-Mobile Arena in Las Vegas. A no contest, also known by its abbreviation "NC", occurs when a boxing match or mixed martial arts fight ends for a reason that is outside of the control of both of the fighters. Neither a winner or loser is deemed in the result of a no contest boxing or MMA fight. The reasons for a no contest decision vary, but the impetus for the fight to end must be either an ‘Act of God’ or indirectly related to the efforts of the fighters themselves. For instance - Mark Hunt fought Brock Lesnar at UFC 200 in July of 2016. A no contest occurs when the fight must be ended for a reason deemed out of the control of both fighters.
