Kevin Pietersen has been fined 5,000 Australian dollars for referring to an umpiring decision as an "absolute shocker" during the Big Bash League semi-final between Melbourne Stars and Perth Scorchers.
Former England batsman Pietersen - who has also confirmed he will not be part of the Indian Premier League auction this year - was left incensed when Perth batsman Sam Whiteman was given not out following an appeal for caught behind.
When asked on air by Network Ten for his opinion on the decision, which umpire Shawn Craig later said he got wrong, Pietersen said: "Shocker. Absolute shocker.
"He said it could have been glove or it could have been pad. I said, 'Well, he's got big gloves and big pads to reach that'.
"Massive. Massive nick."
Cricket Australia (CA) has consequently charged Pietersen with a breach of its Code of Conduct, specifically for making a "public or media comment that is detrimental to the interests of cricket, irrespective of when or where such comment is made".
CA added that Pietersen has 48 hours to lodge an appeal.
The big-hitting batsman, who has largely become a Twenty20 specialist since his acrimonious sacking from England, is also opting not to play in the lucrative IPL this season.
FYI - I won't be going into the IPL auction. My winter has been too busy with all my travel & I don't want to spend April/May away too!-- KP (@KP24) February 3, 2017
Pietersen only played four matches for Rising Pune Supergiants in the 2016 tournament before tearing a calf muscle and cited a busy schedule for his decision.
