Though the IPL statement did not specify why Kohli was being fined, it is likely to do with his reaction to his dismissal for 18 off 7 balls, in the third over of RCB's chase of 223.

According to the technology, the ball would have passed the batter at 0.92 metres from the ground if Kohli was upright at the crease. The height of Kohli's waist had been measured beforehand at 1.04 metres, which means the ball would have passed below his waist had he been on his crease and not outside it, making it a legal delivery.

Kohli was unhappy with the decision and was seen expressing his displeasure to the on-field umpire, along with the non-striker Faf du Plessis, who also thought it should have been a no-ball for height.

To remove the subjective element in adjudicating no-balls above the waist this season, the IPL introduced technology to measure the height of the delivery as it passes the batter at the crease. That is then measured against the toe-to-waist height of the batter when in an upright position, which is recorded in advance. If the height of the ball is more than the recorded height of the batter's waist, then it is declared a no-ball. Otherwise it's a fair delivery.

In this case, the projected trajectory of the delivery would have taken it 0.12 metres below Kohli's waist had he been upright on his crease.

"Obviously, the rules are the rules," RCB captain du Plessis said after the game. "Virat and myself at that stage thought that possibly the ball was higher than his waist. I guess they measure it on the popping crease. In those situations, you'll always have one team that's happy and one team that doesn't feel like it's quite the right decision. But that's just how the game works."

RCB went on to lose the game against KKR by one run, and are bottom of the points table with only one win in eight games.
