Lace up those wrasslin' shoes, because the UFC 100 weekend extravaganza just got even more action-packed. The UFC has announced that it will be hosting its first-ever grappling tournament in conjunction with the Grapplers Quest organization as part of the UFC Fan Expo.

It all goes down on Friday and Saturday, July 10 and 11, at the Mandalay Bay Convention Center.

UFC veterans are no stranger to Grapplers Quest. Past competitors have included former UFC welterweight champion Matt Hughes as well as Kenny Florian, Denis Kang, Brandon Vera, Kurt Pellegrino, Mark Bocek, Eliot Marshall, Mike Massenzio and Matt Riddle.

The UFC is expecting that its first competition will be the largest submission, grappling and Brazilian jiu-jitsu tournament in history.

To help draw the talent, the tournament will give out thousands of dollars in prizes across a variety of divisions and weight brackets intended to offer men, women and children from all skill levels the opportunity to compete.

And that's not all for the two-day UFC Fan Expo. Additional activities in the works include meet-and-greets with several UFC, PRIDE and WEC fighters along with MMA demonstrations, training sessions, fan-inspired special events, and much more.

And don't forget the UFC 100 weigh-ins on Friday, July 10 -- free and open to the public.

Not too shabby for the milestone UFC event.
