Inter director Piero Ausilio has revealed that the player understands what he has done wrong and will return to the squad immediately.
"Antonio knows he's made a mistake and now understands the stance the coach and the club have taken," Ausilio told La Gazzetta dello Sport.
"Tomorrow the entire squad, including Antonio, will meet up at Appiano to train and prepare in the best way possible for the game on Thursday."
Inter coach Stramaccioni echoed that sentiment.
"From now until the end of the season we'll need the help of everyone, and that includes Cassano," he said.
The win over Catania took Inter above Lazio into fourth in Serie A.
