He told teamsky.com: "My collarbone's a lot more mobile than the last time this happened so I'm hoping I'll be back on the bike sooner rather than later.
"It's frustrating more than anything else. I was happy with the way things went at the Tour Down Under and I was looking forward to building my form at the Ruta del Sol."
The injury is common in cycling and riders tend to return swiftly.
Deignan is recovering at home in Donegal and does not require surgery.
His season target is May's Giro d'Italia, which begins in Belfast and also visits Dublin.
