Five-time Grand Slam champion Maria Sharapova has withdrawn from next week's Cincinnati Open with a forearm injury.
The world number 149 pulled out of the Stanford Bank of the West Classic earlier this month with the injury to her forearm and will now miss Cincinnati as a "precaution" ahead of the US Open that starts at the end of August.
Jelena Ostapenko was set to be her first round opponent in one of the best clashes but she confirmed that she will miss her sixth tournament since her comeback.
"I arrived in Cincinnati yesterday eager to play. However, following the doctor’s advice on-site, as a precaution for the US Open, I am unfortunately withdrawing from the tournament with the left forearm injury I sustained in Stanford," Sharapova said.
"I want to thank the tournament for the wild card opportunity and really look forward to competing here next year."
