Mark Cavendish will miss Belgian one-day race Scheldeprijs due to illness.
The three-time winner missed Gent-Wevelgem and Three Days of De Panne last week through illness and is again unable to take to the start line on Wednesday.
"I am sad to miss a race that is very close to my heart, my first win as a professional," Cavendish said in an Omega Pharma-QuickStep media release.
Mark Cavendish claimed his first race win of 2014 with victory on stage five of the Volta ao Algarve on Sunday. His Omega Pharma-QuickStep team-mate Michal Kwiatkowski sealed the overall title.
Mark Cavendish has set his sights on wearing the yellow jersey when the Tour de France comes to Yorkshire this summer.
