Strikeforce returned to Columbus, Ohio, for Strikeforce: Tate vs. Rousey. The event coincided with the annual Arnold Sports Classic. Nationwide Arena was the host for the event's nine fights, including the women's bantamweight championship bout between champion Miesha Tate and challenger Ronda Rousey.
A trio of former Strikeforce champions was also in action.
Longtime lightweight kingpin Josh Thomson met K.J. Noons to determine the next challenger for current champ Gilbert Melendez. Fighting for the first time since losing his middleweight belt, Brazilian Ronaldo "Jacare" Souza matched up with Bristol Marunde. Finally, Sarah Kaufman looked to reestablish herself in the 135-pound division against Alexis Davis.
