Of the injured, nine have been admitted to hospital for medical treatment, while the others who are not critical are being given first aid.
Jallikattu is usually held during the harvest festival of Pongal in mid-January, but could not be organised in the past three years in view of the ban on the sport.
Amid continuing protests over the ban on Jallikattu across the state, the Tamil Nadu Assembly had on January 23 unanimously passed an amendment bill, clearing the path for conducting Jallikattu without any hindrance.
With the government promulgating an ordinance and subsequently getting a Bill passed in the state assembly allowing Jallikattu, the event is being held in several parts of the state in the past few days.
The government's intervention came after a week-long protest largely by youths, including students, in the Marina Beach in Chennai, and elsewhere in the state.
