The main card for the UFC’s next FOX event has been set, and tickets for “UFC on FOX: Johnson vs. Moraga,” which features a flyweight title fight in the headliner, go on sale May 15.

In the main event, UFC flyweight champion Demetrious Johnson (17-2-1 MMA, 5-1-1 UFC) meets challenger John Moraga (12-1 MMA, 2-0 UFC) in a fight that was delayed from this past month’s TUF 17 Finale when Johnson suffered an injury.

UFC on FOX 8 takes place July 27 at Seattle’s KeyArena. The evening’s main card airs on FOX following prelims on FX and Facebook.

UFC officials on Friday announced an on-sale date of May 17 to the general public, which follows two days of presales. UFC Fight Club members can purchase tickets on May 15 at 10 a.m. PT (1 p.m. ET), and subscribers to the UFC’s e-newsletter can purchase tickets a day early on May 16.

Along with the Johnson-Moraga title fight, UFC on FOX 8 features a co-main event welterweight contenders bout between Jake Ellenberger (29-6 MMA, 8-2 UFC) and Rory MacDonald (14-1 MMA, 5-1 UFC); the UFC debut of final Strikeforce welterweight champion Tarec Saffiedine (14-3 MMA, 0-0 UFC), who meets Robbie Lawler (20-9 MMA, 5-3 UFC); and a women’s bantamweight bout featuring Liz Carmouche (8-3 MMA, 0-1 UFC) vs. Miesha Tate (13-4 MMA, 0-1 UFC).

The UFC most recently visited KeyArena in Seattle in December for UFC on FOX 5, which featured Benson Henderson‘s lightweight title defense against Nate Diaz.
