Conmebol have issued a temporary order after the death of a young fan at the Brazilian club's game with San Jose
The ban will remain in place until the South American football federation make a final ruling on the matter.
During Corinthians' first defence of the trophy against San Jose in Oruro, a firecracker was launched into San Jose fans from the away section, killing a Bolivian supporter. The object penetrated the young fans eye and he died before reaching hospital.
Fans of the World Club Cup winners will be denied admission to next Wednesday's home tie against Colombian side Millonarios and subsequent home matches against Tijuana and San Jose.
83,500 fans were hoping to attend the three games in Sao Paulo's Pacaembu stadium.
According to local reports, 12 supporters have also been charged with homicide after events at San Jose's Jesus Bermudez stadium.
