The Ultimate Fighting Championship on April 2 is scheduled to make a return to its roots when UFC Fight Night 13 takes place in Broomfield, Colo. And it appears that they’re looking to return in a big way.

Most of the UFC’s fight cards of late have been expanded to 10 bouts. The Colorado card is one such card, with 10 fights already officially announced by the promotion. But MMAWeekly sources close to both camps on Wednesday confirmed that Kurt Pellegrino and Nate Diaz have signed to fight on the event, boosting the card to 11 bouts.

Not only that, but Dave Meltzer of the Wrestling Observer on Wednesday also reported that UFC officials have confirmed a bout between Manny Gamburyan and Jeff Cox for the April 2, making it a 12-bout fight card.

Part of the event will air live on Spike TV, which is expected to announce an expanded telecast of three hours. Fight Night 13 will serve as the lead-in to season seven of the popular reality series The Ultimate Fighter.
