Juan Martin Del Potro is a doubt for the French Open later this month after revealing he has a torn hip muscle.
The former US Open winner pulled out of last week’s Madrid Masters and after undergoing tests on his injury admitted he may struggle to start in Paris on May 22.
“The results of my tests showed a tear in the hip,” the Argentinian wrote on his Twitter page. “I have already started rehabilitation and I will do all I can to be in Paris.”
Del Potro, who reached the semi-finals at Roland Garros two years ago, has been beset by injury in recent times and missed most of last year with a wrist complaint.
