Indian captain Mahendra Singh Dhoni refused to let a potential controversy take the shine off the thrilling tie played out at the Adelaide Oval on Tuesday.

Chasing a testing target after Dinesh Chandimal's 81 and Mahela Jayawardene's 43 had pushed Sri Lanka to 236 for nine, India rode on the back of Gautam Gambhir's 91 and Mahendra Dhoni's unbeaten 58 to draw the scores level.

Requiring a boundary off the final ball of the match to triumph and all but seal a berth in the ODI tri-series final later this month, Dhoni could only strike Lasith Malinga's fullish delivery for three, with Sachithra Senanayake putting in a superb diving stop in the deep cover region to prevent the winning run.

With the humdinger clash ending in a deadlock, it later emerged that the match umpires - Nigel Llong and Steven Fry - had allowed the 30th over of India's innings to last just five balls, meaning Sri Lanka had faced 300 legitimate deliveries to the opposition's 299.

"Coach Duncan Fletcher told me there was a five-ball over," said Dhoni. "We have seen this in the past. We've bowled an over and almost changed sides but the third umpire interferes and says you have to bowl one more ball in this over. Usually that's what has happened in the past.

"It didn't happen in this game - I don't know why. Not much can be done now. A dot ball could have happened. It's done and dusted. We could create a big fuss out of it, but what's the point? It's like a controversy that's really standing right on the edge, just about to happen. We don't really want to create a controversy out of it.

"We just want to stick to the result that has happened. Hopefully it won't be replicated, not with us or any other side."

Dhoni, part and parcel of India's ongoing stance against the full use of the Decision Review System in ODI and Test cricket, remained adamant that human error is an understandable facet of cricket.

"If this can happen, I don't know why people can back the DRS so much," he added.

"We have seen people being really happy with DRS in one series when it goes in their favour and then it doesn't go in their favour, they're quite unhappy about it. "I'm quite happy with the two umpires in the middle, the third and fourth umpires, the match referee and the scorer. If that ball-counting error still happened, it's better off accepting it, because as humans we are bound to make mistakes.

The next fixture of the tournament sees Australia take on Sri Lanka at the Sydney Cricket Ground on Friday.
