Ronaldinho banned for three Italian Cup ties
The Italian league announced the verdict in a statement having waited two months to decide because it was waiting for the completion of the round.
Ronaldinho was on the ball when he swung an elbow at Lazio defender David Rozehnal, but the incident was missed by the referee.
The Italian Cup has never been a priority to Milan but he will miss the first match of next season's competition. If the Rossoneri are knocked out early, his ban will be rolled over to the following season.
