After trapping Warner plumb in front of the wickets, Jadeja started celebrating wildly even before the umpire had raised his finger during Australia's second innings.
Jadeja signalled Warner the way back to the pavilion.
After the send-off, Dar, who was standing at square leg, cautioned Jadeja. Dar called Tendulkar, who in return spoke to Jadeja.
Jadeja was also involved in a verbal tussle with Warner Saturday during India's first innings when both skippers, Mahendra Singh Dhoni and Shane Watson, had to intervene to stop the spat.
Jadeja could be fined up to 50 percent of his match fees if match referee Ranjan Madugalle of Sri Lanka finds him guilty of violating the International Cricket Council (ICC) code of conduct.
