Russian tennis star Maria Sharapova pulled out of the Rogers Cup Wednesday, citing a "very bad" stomach virus.
The world's No. 2-ranked player said her stomach first began giving her trouble during the Olympics last week and that the quick turnaround left her with little time to recover.
"I think this year we don't have much choice, unfortunately," she said of the short time between tournaments.
"It's once in four years that we have the Olympics."
She said she also has to think about the U.S. Open that begins later this month. "You kind of have to make the smart decisions for your body."
By withdrawing from the Rogers Cup, Sharapova misses out on a chance to take over the WTA Tour's top spot, which she could have done by outperforming No. 1-ranked Victoria Azarenka.
Tournament director Eugene Lapierre said he understands why the star decided to rest.
"It's disappointing for our fans and for all of us, but it's part of the game, unfortunately," Lapierre said in a statement.
"Maria showed exceptional professionalism making the trip to Montreal, coming on site and (trying) to practice, despite the fact she had not been feeling well."
Sharapova will be replaced in the draw by Kazakhstan's Galina Voskoboeva, who had lost to France's Aravane Rezai in the final qualifying round.
