The Super Kings were reeling at 24 for 4 before fifties from Ambati Rayudu and Dhoni revived their hopes.
Tahir removed an ominous-looking Chris Lynn (82 off 51 balls; 7x4, 6x6) and in a space of four balls removed the unsafe Andre Russell (10) for the first time under a score of 40 this season to put brakes on their scoring.
The batsmen (Ravindra Jadeja and Mitchell Santner) took two from the Santner mistimed pull off the waist- high full toss towards wide long on. Dhoni was dismissed by Stokes on the third ball of the over but Mitchell Santner's last ball six ensured that the defending champions got over the line with four wickets to spare. The scene was as freakish as it could get as even Stokes tried to pacify the man who is famously called "captain cool".
It all happened on the first ball of the last over when CSK required 18 runs to win the match.
He was subsequently fined 50% of his match fee.
"MS Dhoni, the Chennai Super Kings captain, was fined 50 per cent of his match fees for breaching the Indian Premier League's Code of Conduct during his team's match against Rajasthan Royals at Jaipur", the league said in a statement. Known for his "captain cool" tag, Dhoni's anger had unsettled a lot of people and many felt he had set up a bad precedent through his gesture.
Former Australia pacer Shaun Tait also lashed out at Dhoni.
Hussey went on to say that Dhoni is a huge asset to any team, a brilliant player who can play to any situation of the game well. Because if he did this, tomorrow another captain can do the same.
".There was confusion. Our understanding was that the umpire at the bowler's end called a no-ball and then there was confusion around whether there was no-ball or not", Fleming said.
"I feel he shouldn't have come to the ground when there are two CSK members already and they were equally inquisitive regarding the no-ball", he opined.
Echoing Slater, former India wicketkeeper Deep Dasgupta said: "He's got every right to go and speak to the fourth umpire, he's got every right to speak to the match referee. but walking in while the game is on (is wrong)".
