The flat stage into Zeeland on the North Sea coast of Holland was blighted by crosswinds and bad weather for the latter part of the course, which saw a number of riders crash, including the Australian.
Hansen said the bunch moved quickly from one side of the road to other in the powerful crosswinds along the route, and he had nowhere to go but into the grass on the side of the road, along with an Ag2r-La Mondiale rider. Hansen fell on the same shoulder he'd injured at the Ster ZLM Tour in June, which he subsequently abandoned.
The 34-year-old has finished every Grand Tour on the calendar since the 2011 Vuelta a España and would not easily give up on riding a record 12th Grand Tour in a row. Hansen got back on his bike, albeit visibly in pain and clutching his right shoulder. He rolled in 11-06 down on teammate André Greipel, who won the stage ahead of Peter Sagan (Tinkoff-Saxo).
Hansen was taken to hospital in nearby Antwerp for x-rays, which later confirmed that he had suffered a dislocation to the AC joint.
Lotto-Soudal confirmed late on Sunday night that Hansen would continue at the Tour, along with Thomas de Gendt, who injured his knee in a crash.
