( CNN) Maria Sharapova will have to wait until the US Open in August — at the earliest — to return to grand slam action after the Russian superstar pulled out of Wimbledon qualifying due to hurt.

Sharapova came back to the tennis tour in April after a 15 -month doping forbidding but with her ranking has still not been good enough to attain the main draw needed a wildcard to enter the ongoing French Open.

But after being denied that wildcard by the French tennis federation, the five-time grand slam win — and world’s richest female athlete for most of the past few decades — decided to enter Wimbledon qualifying in the final week of June instead of requesting a main-draw wildcard.
