Gesias "JZ" Calvancante (Pictures) was contacted by Dream staff early Wednesday and informed of Shinya Aoki (Pictures)'s withdrawal from the May 11 Dream lightweight grand prix semifinals, a source from Calvancante's camp told Sherdog.com Wednesday.

Aoki suffered a facial injury in Tuesday's bout that saw him outpoint Calvancante after two rounds.

Calvancante was approached about replacing the Japanese fighter, but the 24-year-old American Top Team representative could not come to terms with the promotion and has since left Japan.
