Mark Cavendish will undergo shoulder surgery on Wednesday and faces around six weeks out following his Tour de France-ending crash on stage one in Harrogate last Saturday.
The 29-year-old from the Isle of Man ruptured all ligaments around his acromioclavicular joint and a separated shoulder as he sought a first yellow jersey of his career, his Omega Pharma-QuickStep team has confirmed.
"The surgery to stabilize the AC joint will take place on Wednesday, July 9," the Belgian squad said in a statement.
"The recovery time after the surgery will be around six weeks."
It means the Manxman will miss the Commonwealth Games in Glasgow.
