A welterweight bout between Mike Guymon and Daniel Roberts is in the works for the preliminary card of “UFC 121: Lesnar vs. Velasquez” on October 23 at the Honda Center in Anaheim, California, MMAjunkie reports.

Both Guymon (12-3-1) and Roberts (10-1) dropped their UFC debuts earlier this year before recently earning their first UFC wins.

Guymon, a former King of the Cage champ, had his five fight win streak snapped with a loss to Rory MacDonald in January, but “The Joker” bounced back in May with a unanimous decision over Yoshiyuki Yoshida at UFC 113.

Roberts suffered his first career loss with a first-round KO to rising 170-pounder John Howard in March, but rebounded earlier this month with a split decision over late-replacement Forrest Petz at UFC 116.

The UFC 121 fight card is headlined by heavyweight champ Brock Lesnar vs. Cain Velasquez and also features Jake Shields vs. Martin Kampmann and Tito Ortiz vs. Matt Hamill.
