UFC on FOX 8 is starting to fill up, despite no main event having been announced for the card yet.

Two new additions were made official by the UFC on Tuesday, as Michael Chiesa takes on Reza Madadi and Yves Edwards battles Spencer Fisher.

The card goes down July 27 from the KeyArena in Seattle. Jake Ellenberger-Rory MacDonald and Robbie Lawler-Tarec Saffiedine are the two biggest bouts announced to date.

Chiesa (9-0) is a former winner of The Ultimate Fighter, while Madadi (13-3) has gone 2-1 in his UFC career.

Edwards (42-19-1) and Fisher (24-9) are likely fighting to remain in the promotion, as both are coming off defeats.
