Kamui, 23, made his Grand Prix debut in Brazil, where he qualified 11th and finished ninth after a fighting performance.
He once again replaces Timo Glock, who suffered a cracked vertebra and cut leg in an accident during qualifying for the Japanese Grand Prix earlier this month.
President John Howett said: "We feel genuinely sorry for Timo that his season, which has included two impressive podium finishes, is ending in this way. Having discussed the medical advice with Timo and his management, the team has decided to take no risk and to put Kamui in the car. Kamui performed well in Brazil in difficult circumstances so we are happy to ask him to once again deputise."
