Kyrgios was due to play Spain's Roberto Bautista Agut in the first round in Rome, but was replaced by lucky loser Alexandr Dolgopolov in the men's draw.
Kyrgios, who won two matches at last week's Madrid Open before losing to eventual champion Rafael Nadal, needed treatment for a hip complaint during his first-round win over Marcos Baghdatis in Spain.
