Due to a shoulder injury, Gleison Tibau had to withdraw from his bout with Hermes Franca at UFC 90 and will be replaced by Marcus Aurelio, according to Sherdog; the bout would be the first for Aurelio since his loss to Tyson Griffin at UFC 86 while Franca is coming off a loss himself to Frankie Edgar at UFC Fight Night 14 and his first fight back in over a year when he was suspended for testing positive for steroids following his loss to Sean Sherk at UFC 73 in July 2007.
