Erick Silva was expected to face Jay Hieron at the Rocksville event; however, Silva pulled out of the bout citing an injury, and was replaced by promotional newcomer Tyron Woodley.

A date between Robbie Peralta and Akira Corassani was briefly linked to this event; however the bout was rescheduled for April 6, 2013 at UFC on Fuel TV 9 after Corassani was sidelined for a short period with an illness.
