The official website of the Indian Premier League confirmed the news.
"As it was his team’s first offence of the season under the IPL’s Code of Conduct relating to minimum over-rate offences, Mr Dhoni was fined Rs 12 lakh," a statement on iplt20.com read.
In the post-match presentation, MS Dhoni said that a 7.30 pm start in IPL 2021 will mean that teams batting first will have to score at least 200 runs to put the side batting second under pressure. Dhoni's comments came after his team lost to Delhi Capitals (DC) by seven wickets here on Saturday.
CSK had put up an imposing 188/7 in their 20 overs, batting first, but DC reached the target for the loss of just three wickets and in the 19th over.
Chennai fielders dropped a couple of catches to let off opener Prithvi Shaw, too.
