Rocha broke the news via his official facebook account.
UFC on FX 3 is tentatively scheduled for June 8, but a location and venue have yet to be revealed by company officials.
Pierce last saw action at UFC 143 where he lost a razor thin decision to top welterweight Josh Koscheck. The loss marked his second UFC loss in six official outings.
Rocha is a “Team Black House” member who gave Jake Ellenberger all he could handle at UFC 126, but he lost. Having been put on the sidelines due to injury for more than a year this booking signifies his health and ability to return to action. Prior to the Ellenberger loss he was undefeated.featured, MMA NEWS, Strikeforce, strikeforce news, ufc news, UFC on FOX, UFC on FOX 2, ufc on fox 3, UFC on Fuel, UFC on FX
