Rousey defeated Alexis Davis in their bantamweight championship match, landing 14 significant strikes in 16 seconds. De Randamie defeated Aspen Ladd in a bantamweight match: Aspen subsequently failed in her appeal to have the match declared a No Contest, following the referee’s contentious decision to halt their fight after 16 seconds.
Amanda Nunes KO’d Julia Budd in 14 seconds at Strikeforce Challengers on 7 January 2011. Strikeforce was subsequently purchased by UFC’s parent company Zuffa, LLC.
