Kevin Pietersen has been given an official reprimand for his reaction to being given out in Saturday's Twenty20 win over India at Eden Gardens.
The 31-year-old, who top-scored with 53 to lead his side to victory, was adjudged lbw by umpire Sudhir Asnani despite the ball from Suresh Raina appearing to pitch outside leg stump.
Match referee Roshan Mahanama said: "Kevin should know that when the umpire raises his finger, a player should leave the crease without showing emotion no matter what he may think of the decision. In this case, Kevin displayed excessive and obvious disappointment at the decision which sent the wrong signals to all those watching the match and, as such, merited some form of action."
Pietersen was found to have committed a level one breach of the International Cricket Council's code of conduct, the maximum punishment for which is a fine of 50 per cent of a player's match fee.
