"All athletes have niggling injury issues they have to face and I am no different. This is not a career-ending injury but the timing is extremely disappointing," Pearson said.
Pearson is targeting a third consecutive gold medal in the 100 metres hurdles event at the Commonwealth Games after winning at the New Delhi Games in 2010 and in Glasgow four years ago.
"Australia can rest assured I will be certainly working hard to overcome what is just another challenge in my career."
Australia head coach Craig Hilliard said Pearson was on a restricted training programme in the lead up to the event.
"Sally is completing her key training sessions on a modified training load to optimise her final preparations for both the 100 hurdles and 4x100 relay events," Hilliard said.
The Commonwealth Games will be staged from April 4-15 on the Gold Coast, Queensland.
