Jackie Chan hurt his chest again while filming a fight scene for "Rush Hour 3," although doctors have cleared him of major injury, the veteran action star said in his online diary recently.

Chan first injured his chest in March, while shooting his recent action comedy "Rob-B-Hood," when a stunt man wearing the wrong shoes kicked him.

Chan said he got hit in the same area by a steel-reinforced wooden table while shooting a fight scene for "Rush Hour 3."

"I was in a lot of pain because it was in the same spot where I had gotten hurt during the filming of "Rob-B-Hood," he said.

Chan said he tried to work through the pain, wearing a stunt belt across his upper chest and taking medication, but the movie's producers eventually sent him to a doctor. An X-ray cleared him of broken bones or organ injury, Chan said.

Chan has suffered numerous injuries throughout his career. One of his worst was a brain haemorrhage while filming "Armour of God." He said in an interview last year, he usually feels pain in his waist, knees and shoulders when he wakes up.

The action star also said he's impressed with the spoken English of rising Chinese actress Zhang Jingchu, who has a part in "Rush Hour 3."

Chan said Zhang, whose credits include "Seven Swords" and "Peacock," has shown good acting skills, but that he was "also surprised that her English was so good."
