Ajith hurt his right knee when he was trying to jump from one speeding to car to another while shooting for a stunt sequence last Saturday for his next movie in Mumbai.
'Ajith had to stand on the bonnet of car with a gun in one hand. So when he performed the sequence, he lost balance and hit his knee while landing on the other car,' says a source.
Director Vishnuvardhan and the cinematographer, who were present when this unfortunate incident happened and seem to have taken him to a hospital later.
The doctors have apparently told him that a ligament in his right knee has been torn and has advised him to undergo surgery. 'But Ajith refused and has been continuing to shoot till now. He might decide about the surgery only when he returns to Chennai after wrapping the current schedule,' says the source, adding, 'Ajith was operated for the same right ligament tear a few years ago.'
