Robertson replaces injured Maloney
Scotland boss George Burley had already lost Danny Fox, Robert Snodgrass, Kevin Thomson and Garry O'Connor from the squad for Saturday's friendly game in Yokohama.
Defender Lee Wallace of Hearts was called up to the senior squad for the first time, joined by striker Lee Miller of Aberdeen.
Burley could face further upheaval later on Tuesday as Scott Brown visits a London specialist over his ongoing ankle problem, which forced him to miss the start of the season.
The Celtic midfielder is seeing a Harley Street expert after failing to make a complete recovery despite undergoing surgery in May.
Burley's squad assembled for training on Tuesday at Dumbarton but several of his stars arrived with knocks and only 10 outfield players took part in the session.
