Jonas Vingegaard was taken to hospital after a massive crash during stage four in the Tour of the Basque Country on Thursday, which also involved Primoz Roglic and Remco Evenepoel.
The crash happened at high speed on the descent from the Olaeta climb with 35.9 kilometres remaining when one rider went down causing a chain reaction, and Vingegaard was still on the ground receiving medical treatment several minutes later.
"The stage has been neutralized. Jonas is on his way to the hospital. An update will follow later," Vingegaard's Team Visma-Lease a Bike said on social media platform X.
Vingegaard was taken away on a stretcher wearing a neck brace. Evenepoel was also taken to hospital and abandoned the race.
"The race is neutralized until the finish line, the six leading runners will compete in the stage but the stage times will not be counted for the general classification. The peleton will go in neutral until the finish line," race organisers said.
