A lightweight bout between Danny Castillo and Alex Karalexis was once attached to this event, though it was later scrapped. Both men remained on the card with new opponents, as Castillo was matched with Shane Roller, while Karalexis was expected to face the debuting Kamal Shalorus. However, Karalexis had to bow out of the Shalorus matchup due to a broken hand, and was replaced by fellow WEC newcomer Will Kerr.
The event drew an estimated 414,000 viewers on Versus.
