4. Harbhajan Singh and S Sreesanth in IPL 2008
The very first season of the IPL saw two Indian players involved in an ugly spat. Kings XI Punjab had defeated Mumbai Indians in a match and the players of two teams were doing the customary handshakes after the match. The Mumbai skipper Harbhajan disappointed from the loss out of the blue slapped his Indian teammate Sreesanth.
This left everyone stunned on the ground as nobody expected this to take place. Sreesanth was seen with tears while his other teammates tried consoling him. Harbhajan was banned for the remaining of the IPL season as he inappropriately slapped Sreesanth after the match.
