Cat Zingano is coming off a torn ACL and horrible family tragedy. Alexis Davis struggled to beat Jessica Eye. Julianna Pena is out for who knows how long with a torn knee and hamstring.

There's really only one legitimate contender out there for Ronda Rousey after UFC 170 on Saturday night. Yeah, you know exactly where this is going.

The UFC must book Rousey against Cris Cyborg before the end of 2014. It's the only thing that makes sense. If the UFC is truly committed to women's MMA, it absolutely has to put together the two best female fighters in the world.

"Of course I'm interested in it," Rousey said on FOX Sports 1 after her first-round knockout win over Sara McMann. ... "I'm not going anywhere. She knows where I'm at."

Zingano will probably get the next women's bantamweight title shot. That's fine. She's undefeated as a pro and earned the No. 1 contender slot when she beat Miesha Tate last June.

I'm not going anywhere. She knows where I'm at.
