The UFC made the announcement just one day after the news came out that Miesha Tate would be fighting Cat Zingano on Apr. 13 at the TUF 17 finale.
There are now a total of six females officially signed to the UFC.
Ronda Rousey will fight Liz Carmouche on Apr. 6, in the main event of UFC 157 in Anaheim, Calif., which will serve as the first all-female fight in UFC history.
Tate and Zingano will fight for what is likely to be a No. 1 contender bout for a chance to fight Rousey for her belt sometime over the summer. McMann and Davis are also set to fight each other. However, the UFC has not made that bout official.
McMann, a former Olympic medalist who recently defeated Shayna Baszler at Invicta FC 4, holds a perfect 6-0 professional record.
As for Davis, she has rattled off wins in five of her last six outings, with her past two victories coming under the Invicta banner. The former Strikeforce fighter holds a 13-5 mark overall.
Rousey, Carmouche, Tate, Zingano, McMann and Davis are the only current females signed to UFC contracts, but there's absolutely no way the bantamweight division will remain a pool of just six competitors.
Here's a look at the next five females most likely to join the UFC ranks.
