The 2-time Olympic 100m champion Fraser-Pryce injured her toe earlier this month and was forced to withdraw from her three previous events; on May 7 in Jamaica followed by two Diamond League events in Shanghai and Rabat.
"She is training, albeit not as ideally as she would like," her coach Stephen Francis told local Jamaican TV.
"But she is back in training and has been for the last week and a half and she has to go to Prefontaine this weekend, so we'll see what happens.
"But I think she will be ready to compete ... it's just that she has a lot of pain when she does train, but now I think we have found a way around it and in another three to four weeks she will be ready to go."
This Saturday, Fraser-Pryce will race the 100m facing world's top sprinters.
