Jadeja started wildly celebrating Warner's dismissal after trapping him plumb in front even before the umpire had raised his finger during Australia's second innings at the Feroze Shah Kotla stadium.
Jadeja showed Warner his way back to the pavilion to which Dar, who was standing at the square leg, took exception.
Dar called up Sachin Tendulkar, who in return spoke to Jadeja.
Jadeja was involved in a verbal spat with Warner yesterday during India's first innings when he had shown the handle of his bat to the Aussie opener.
