We knew that Ultimate Fighting Championship (UFC) was putting the pieces together for its most loaded FOX fight card ever, now we know where it's going to take place.

UFC on Fox 5 will emanate from the KeyArena in Seattle, Wash., on Dec. 8, 2012, according to a report this evening on FUEL TV's "UFC Tonight."

This is not the first time that the world's leading mixed martial arts (MMA) promotion has invaded the "Emerald City." In fact, UFC Fight Night 24: "Davis vs. Nogueira" took place back in March 2011, featuring a main event that saw Phil Davis earn a unanimous decision over Antonio Rogerio Nogueira. In the co-featured fight of the night, Anthony Johnson wrestled his way to victory over Dan Hardy.

Rest assured fans in the venue, as well as those watching in their living rooms, won't be disappointed with the stacked sophomore Seattle effort.

UFC on FOX 5 will be headlined by a lightweight title fight between reigning 155-pound champion Ben Henderson against division number one contender Nate Diaz. In addition, Alexander Gustafsson will try to move to the head of the light heavyweight class when he tangles with former 205-pound champion Mauricio Rua, while B.J. Penn vs. Rory MacDonald will meet in a Welterweight scrap that pits the old opposite the new school.

Oorah!
