Paris: World number four Agnieszka Radwanska has pulled out of next week's Brussels WTA tournament in a bid to protect her injured shoulder ahead of the French Open.
The Polish star has been carrying the injury throughout the claycourt season where she lost in the second round in Madrid as well as Rome.
"I have had some shoulder problems for a while & on clay it's getting a bit worse," Radwanska tweeted.
"I'm afraid it might get even worse, with RG (Roland Garros) and grass coming up. So I felt I had to pull out. It's upsetting, I wanted to defend my title."
The French Open gets underway in Paris on May 26.
