On Tuesday July 29 morning UK time, multiple videos captured by journalists at the venue showed Gambhir having a heated argument with Fortis during India's training session at the Oval.
While it's still unclear what the argument was about, Gambhir was seen pointing a finger at Fortis and saying "You can't tell us what to do". He kept repeating the same, even saying at one point: "you're just a groundsman, stay in your capacity".
Sitanshu Kotak, India's batting coach, stood next to Fortis and had a long discussion, even as the players continued training.
It reached a point where Kotak, as well as Ryan ten Doeschate India's assistant coach were seen pacifying Fortis. At one point, Fortis is heard saying that he will report Gambhir.
