The ongoing Test series between India and South Africa has got heated up with fierce competition at the Wanderers and exchange of words between the players from both sides. 

Constant sledging from Indian fielders on Day 3 of the second Test went to an extent when even the on-field umpire Marais Erasmus felt the intensity. Erasmus was heard telling the Indian players that they are giving him a 'heart attack' every over.

The incident took place in the 10th over of South Africa's second innings, in which Aiden Markram was dismissed off the final delivery by Shardul Thakur. Before getting rid of Markram, Shardul made two strong appeals against the batter when the Indian fielders passed on a few words.

After the over when players were changing sides, Erasmus was heard saying, “you guys are giving me a bloody heart attack after every over” on the stump mic. 

Here is the clip:

India's wicketkeeper Rishabh Pant was sledged by Rassie van der Dussen when he came out to bat in the second innings. He then got dismissed the next delivery after having a word with Dussen. 

Pant, who was upset over the exchange, gave it back to the South African batter when he walked in to bat. However, Dussen managed to survive the last session of Day 3 and scored 11* off 37 deliveries before stumps.

Even when India pacer Jasprit Bumrah was batting on Day 3, he and South African young fast bowler Marco Jansen walked up to each other in a heated moment. The umpire had to step in and cool down the situation.
