Nadal to decide this week on fitness to defend U.S. Open

"He went for a check (up) today in Barcelona and (the) imagery looks as predicted. He will practise in the next days and decide on Friday or Saturday," his spokesman said ahead of the U.S grand slam which starts later this month.

The 28-year-old Majorcan left-hander sustained the injury during practice last month and has been training with a cast on his right wrist.

Nadal was forced to withdraw from last week's Rogers Cup in Toronto and this week's Cincinnati Open, putting in doubt his participation at the year's final grand slam at Flushing Meadows in New York starting on Aug. 25.

Last week the world number two posted a picture of himself working on court with his uncle and coach Toni in which a black wrist support was clearly visible.

"Making the most of these days to continue training, always with desire and optimism," Nadal wrote.
