Chicago midfielder Bastian Schweinsteiger (right thigh injury) was listed as questionable.
Five Fire players were listed as out for John Goossens (right ankle surgery), Jorge Bava (left elbow surgery, Daniel Johnson (left MCL injury), Christian Dean (fifth metatarsal fracture) and Michael de Leeuw (ruptured left ACL).
