Ronda Rousey will defend her Strikeforce bantamweight title for the first time later this summer.

According to sources close to Strikeforce, Rousey will meet top contender Sarah Kaufman at a yet-to-be announced Strikeforce card in August. No date or location has been finalized yet.

Rousey (5-0) defeated Miesha Tate in March to capture the Strikeforce women's 135-pound belt. The win capped off an impressive year which saw her win her first five fights in a combined time of 7:15.

Kaufman (15-1) secured her spot as the No. 1 contender when she defeated Alexis Davis on the same card in March. The Canadian has won three in a row since losing the 135-pound belt to Marloes Coenen in Oct. 2010.

The card will air on Showtime.

Strikeforce returns on May 19 with an event headlined by Daniel Cormier vs. Josh Barnett and Gilbert Melendez vs. Josh Thomson.
