British pair Iain Percy and Andrew Simpson have been forced to withdraw from the World Championships due to Percy's back injury.
The defending champions and Olympic gold medallists led the standings in the Star class on Tuesday.
"We're really disappointed to have to pull out," said Percy, who will compete with Simpson at the 2012 Olympics .
"We were having a great regatta, were sailing well and were really enjoying the racing."
The double Olympic gold medallist added: "We haven't done a lot of racing recently so it was great to be racing together with Bart again, and to be racing as well as we were.

“We've done a lot of racing over the past 10 days. I think we've done 35 matches, but we are in the groove and it feels really good to get that amount of racing in”
"It's certainly frustrating, but it's more important for me to concentrate on getting fixed and fit again so that this doesn't happen when it really matters at the Games next summer."
The news comes a day after Ben Rhodes's rib injury ended his involvement in the 49er class alongside Stevie Morrison.
Defending world champions Lucy Macgregor , Annie Lush and Kate Macgregor have sealed their place in the semi-finals of the women's match race event with a 3-1 victory over the Dutch crew of Mandy Mulder, Merel Witteveen and Annemiek Bekkering.
The British trio had to race an additional 15 matches - winning 13 of them - just to make the quarter-finals after a disappointing round-robin performance and will face the French team, skippered by Claire Leroy, in Thursday's semi-final.
