Cape Town - India batsman Gautam Gambhir was given a four-match ban from first-class cricket after an altercation with Delhi coach KP Bhaskar earlier this year.
Gambhir, who is Delhi's captain, criticised Bhashkar in March during the Vijay Hazare Trophy competition for making the younger members of the squad feel insecure.
The left-handed Gambhir has been found guilty of "seriously inappropriate behaviour" by an enquiry committee that was set up by the DDCA.
The committee said in a statement: "The Committee Members agree that considering the above facts and circumstances that have come to light, Gambhir's actions towards Pillai with premeditated intent to humiliate the coach were highly inappropriate and of serious nature.
"The position of a coach among the team members is of high respect and dignity. It is a serious disgrace to a coach to be humiliated in front of team members by one of the team members even though if it is a senior player.
"The actions of Gambhir, however well intended, cannot be said to be in the interest of the team, or its performance or the game as it was done on the very last day of the season and therefore could not have been any corrective effect."
