Paris - Former U.S. Open champion Andy Roddick has pulled out of this week's Nice Open with a shoulder injury and may not be fully fit for the French Open starting on Sunday.
"It is not ready to play yet, I hurt it last week in Rome," the American world No 11 said in a video on the Nice Open official website on Tuesday.
"It's running a big risk playing on an unhealthy shoulder with Roland Garros round the corner and Wimbledon shortly afterwards.
"I'm pulling out of Nice for now, obviously the situation is not perfect for Roland Garros."
The 28-year-old's best result at the French Open is the fourth round in 2009 given he is not a clay court specialist but he has reached three Wimbledon finals. He won the 2003 U.S. Open.
