Adriano cause controversy on Friday when he arrived late for training, left early and threatened a cameraman.
The striker, who has joined the Brazilian champions on loan from Inter Milan in a bid to resurrect his faltering career, could face a fine for his latest misdemeanour, the club said.
"We're going to analyse the facts, to decide whether or not there will be a fine," Sao Paulo general manager Marco Aurelio Cunha told reporters.
"The important thing here is that there is a healthy atmosphere. People have to be happy here and if they are not happy, they don't need to stay."
