Kimo Leopoldo was removed from his scheduled fight against Bas Rutten because he tested positive for the anabolic steroid Stanozolol. The positive drug test results came just two days before the match, leading to his removal from the event. As a result of Kimo's failed drug test, Wes Sims stepped in to replace him in the co-main event of the World Fighting Alliance's "King of the Streets" card.
