The Danish rider came down heavily on Saturday, suffering abrasions to his forehead and face as well as the broken bone.
Cort also broke his collarbone in a crash at this year’s Tour de Yorkshire, though it has not yet been revealed if it’s the same one.
The 24-year-old has signed for Astana from Orica-Scott on a two-year deal, though he will now be unable to take part in the team’s first winter training camp in a week’s time.
“Unfortunately, Astana 2018 newcomer Magnus Cort Nielsen crashed during a training and broke his collarbone,” read an update from the team. “We wish to him a very fast recovery. Get well soon, Magnus, we are waiting for you!”
A fast finisher, Cort won two stages of the 2016 Vuelta a España, including the final leg in Madrid, and also rode regularly in the service of Caleb Ewan at Orica-Scott. The 24-year-old was also part of Orica-Scott’s Classics squad in each of his three years at the team, and he will look to progress further on the cobbles at Astana.
