has confirmed that Matt Arroyo will take on John Kolosci this Saturday at The Ultimate Fighter 6 Finale in Las Vegas. The event airs live on Spike TV beginning at 9pm and includes a main event bout between lightweights Clay Guida and Roger Huerta as well as the finals of the welterweight tournament.

Arroyo (2-1 MMA, 0-0 UFC) was a semi-finalist on the sixth season of the reality series but was unable to face Mac Danzig in the semi-finals after suffering a rib injury while preparing for the fight. Though the doctors did not require him to drop out of the fight he felt the injury significantly affected his ability to fight and opted to withdraw. The move was criticized by UFC President Dana White on the episode but with his injury now healed Arroyo will be appearing on this weekend’s live finale.
