1. The Slapgate
After the match between Mumbai Indians and Kings XI Punjab, the cameras caught a teary-eyed Sreesanth and later it came to light that Harbhjan Singh slapped him. Later, both the cricketers shook their hands at a function to show that they have buried the incident. But what led to the slapping - it still remains a mystery.
2. Lalit Modi sacking
The IPL was the brainchild of Lalit Modi and he had ample support from then BCCI secretary N Srinivasan. In three years - 2008 to 2010 - the league became a household name and stole the thunder from prime time TV shows. But in 2010, Modi was sacked from IPL Governing Council on the grounds of financial misappropriations and the BCCI banned him for life from administrational duties. Modi now lives in London.

Royals and Chennai Super Kings, whose owner Gurunath Meiyappan too was banned for life from cricket administrative duties, were suspended for two years.
4. Teams disbanded
Over the years, Deccan Chargers, Kochi Tuskers Kerala and Pune Warriors were disbanded by the BCCI after financial irregularities and inability to pay the bond to the governing body. While Chargers were the champions of the second season in 2009, Tuskers played just one season and Warriors a very unsuccessful three seasons before getting terminated.
5. Shah Rukh Khan banned
