Ravindra Jadeja was hit on his helmet in the 20th over of Indian innings.
Jadeja was struck on the helmet during the last over of India’s innings, and as BCCI medical team assessed him, he was replaced by wrist-spinner Yuzvendra Chahal as a concussion substitute.

As it turned out, Chahal took 3 wickets by conceding 25 runs in India’s 11-run victory over Australia in the T20I series opener at Canberra on Friday (December 4).
"From our side, it was a right decision as Ravindra Jadeja was not fit to play and could not bowl as well," Sehwag, who is an expert on 'Sony Six', said.
"It was an opportunity which the Indian team got because he was hit on the head and when you are hit on the head, nobody can say that concussion will happen at that time. It takes time. You might get symptoms within 24 hours. So Indian team took the right advantage of the rule," he added.
Chahal replacing Jadeja as a concussion substitute infuriated quite a few individuals in the Australian camp, including head coach Justin Langer.
According to Sehwag, however, Australians shouldn't be complaining as they were the first beneficiaries of concussion substitute rule.
"When Steve Smith was hit on the head, Labuschagne came out to bat in place of him and made runs. So, Australia also got that advantage. So I think Australia shouldn't complain.
"They might have just one contention that Jadeja continued to bat and made runs but when you open your helmet inside the dressing room then you might witness some swelling, you might fell dizziness. There is a possibility.
"I was hit on the helmet many times so I know how it feels but during our times there were no such rules."
