A second world title fight has been added to the UFC 177 lineup, as flyweight champion Demetrious Johnson meets Chris Cariaso.

Set for August 30 from the Sleep Train Arena in Sacramento, California, the main event boasts T.J. Dillashaw vs. Renan Barao for the bantamweight title.

UFC officials were forced to scrap a previous August pay-per-view, and they are loading up the second one now.

Johnson (20-2-1) has successfully defended his title four times since winning it in a tournament final vs. Joseph Benavidez. “Mighty Mouse” is 8-1-1 with the UFC, including two wins over Benavidez and victories vs. John Dodson and John Moraga.

He was expected to meet Dodson in a rematch, but the former Ultimate Fighter winner needs surgery to repair a torn ACL and will be sidelined until 2015.

Cariaso (17-5) has won six of 10 Octagon bouts and was originally booked for a meeting with Kyoji Horiguchi later this year. Cariaso holds wins over Takeya Mizugaki and Vaughan Lee, but was topped while competing at a bigger weight class against Barao and Michael McDonald.

The fight was first reported by Yahoo! Sports.
