An undercard bout has been added to the upcoming UFC 121 show in Anaheim, CA as Daniel “Ninja” Roberts gets back in action against former King of the Cage champion Mike “Joker” Guymon in a welterweight bout on the October 23 card.

The bout was confirmed to MMAWeekly.com by sources close to the fight on Friday and was initially reported by MMAJunkie.com.

Daniel Roberts (10-1) comes into UFC 121 with a split 1-1 record in the Octagon, and after losing his debut to John Howard, he bounced back against late replacement Forrest Petz at UFC 116 with a split decision win.

The California based fighter has been training with Gilbert Melendez, Jake Shields and others at the Cesar Gracie camp in the Bay Area, while also working with Melendez’s team the Scrap Pack as well.

Hope to improve on his own 1-1 record in the UFC when taking on Roberts will be Mike “Joker” Guymon (12-3-1) who much like his opponent had a rocky start in the Octagon, but bounced back with a win in his second fight.

Defeating Japanese Judoka Yoshiyuki Yoshida in May, Guymon will try to keep the momentum going when he faces Roberts in California.

The bout between Roberts and Guymon will fill part of the undercard for the show taking place in Anaheim, CA headlined by heavyweight champion Brock Lesnar defending his belt against Cain Velasquez.
