The accident happened Sunday afternoon.
'It happened when we were shooting some crucial sequences with Aamir. Although he had supported his leg, he got into an awkward position while shooting and he seriously injured himself again. Shooting can wait. Right now we are worried about his well being,' said director A.R. Murgadoss in a press statement.
The star has been asked to take complete bed rest for three weeks and the shooting of the film, which is a Hindi remake of a Tamil blockbuster of the same name, has been delayed till then.
'He will be coming to Mumbai in a day or two once doctors allow him to travel after which he will rest at his Bandra residence,' said a source.
Just last week, Aamir had injured his hamstring while performing an action sequence following which he took rest for a couple of days before getting back to work.
'Aamir did not want the shooting of 'Ghajini' to suffer because of his injury. Everyone on the sets was against him pushing himself, but Aamir was insistent that we should shoot close ups. He spoke to the director and decided to shoot the close up sequences, which wouldn't aggravate his injury,' said a source from the sets.
However, it was a bad idea as his muscle got further strained.
'He was chasing the bad guy and his leg was in an awkward position and now his hamstring muscle is torn. After the shot was canned, Aamir couldn't get up for almost 40 minutes.
'Initially, everyone on the sets thought that Aamir was pulling a fast one, but only when he screamed in pain, everyone got into action.'
A physiotherapist was present on the set and he requested for a specialist to be called in. Aamir had to be carried and was taken to a local hospital.
