Glasgow - Olympic champion Sally Pearson of Australia says she's a doubtful starter for the 100m at the Commonwealth Games due to hamstring problems, though she still hopes to compete in her specialty 100m hurdles event.
The 100m is scheduled for Monday while the hurdles final will be on August 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 100m world hurdles champion.
