The only other official fight on the card is a heavyweight tilt between Gabriel Gonzaga and Travis Browne.
Besides Rousey, Carmouche, Tate and Zingano, no females are signed to the UFC roster, so it makes sense that the fight between Tate and Zingano will determine who fights Rousey next.
UFC President Dana White announced the Gonzaga vs Browne fight via Twitter.
“Heavyweights Gabriel ‘Napao’ Gonzaga and Travis ‘Hapa’ Brown have agreed to fight at the Ultimate Fighter Finale April 13," he wrote.
As for Tate vs Zingano, the bout marks just the second official UFC fight featuring two females. UFC 157 will mark the first all-female fight in the UFC ranks, as Ronda Rousey squares off against Liz Carmouche.
Tate would love another shot at Rousey after losing to her in a Strikeforce fight in 2012, and a win over Zingano would possibly put her in line for a title shot.
For the 26-year-old Tate, it will mark her first time back in the cage since defeating Julie Kedzie in a Strikeforce fight in 2012.
As for Zingano, she's riding a seven-fight win streak, with her most recent victory coming in the Invicta FC ranks against Raquel Pennington.
