MMA or boxing matches called no contest are handled like a draw in which the betting line does not include 'draw' as a wagering option. In simpler terms, you'll generally get your money back if the fight you bet on is called no contest. Online sportsbooks tend to treat these results as a push.

If any selection in any leg is a non-runner or otherwise void under the Sportsbook Rules (e.g. an abandoned match) then all bets on that individual leg will be void and the parlay bet shall be adjusted accordingly. For example a treble including one void leg will become a double.
