The change has not been officially announced by representatives from Fighting Entertainment Group, the parent company of K-1 and Dream. It is unknown if Aoki will stay on the card against a new opponent.
The Dream event takes place May 29 at the Saitama Super Arena in Saitama, Japan. Earlier this week, the promotion announced McKee as Aoki opponent after a series of rumored opponents.
MMAJunkie has reported that, according to McKee, the fighter pulled out due to trouble obtaining a visa.
After a 15-fight undefeated streak, McKee finally received a shot in the UFC. In his promotional debut, he dropped a split decision to Jacob Volkmann at UFC 125. Recently, the MFC announced that both parties “mutually agreed” that McKee should vacate his MFC title.
