Olympic champion Sally Pearson of Australia says she's a doubtful starter for the 100 meters at the Commonwealth Games due to hamstring problems, though she still hopes to compete in her specialty 100-meter hurdles event. (Also read: Aussies target less gold medals, wary of England)

The women's 100m race is scheduled for Monday while the hurdles final will be on Aug 2, the second-to-last day of the games.

Pearson says at a news conference on Wednesday, "the latest I can pull out is 48 hours, and right now it is more likely I am going to. I've had a few discussions with my coach and we're really at the stage where I can't do two events."

The Australian is also the 2011 world hurdles champion.
