Kennaugh signed his first professional contract with Team Sky in September
Isle of Man cyclist Peter Kennaugh has fractured his left collarbone after crashing at the Strade Bianche Eroica race in Italy on Saturday.
The 20-year-old Team Sky rider came off in the third of eight tricky gravel sections in the Siena race.
Kennaugh went straight to hospital but as it was a clean break surgery was not deemed necessary.
Astanta rider Maxim Iglinskiy won the race with Team Sky's Thomas Lofkvist second and Michael Rogers third.
Another of Kennaugh's team-mates, Norwegian Kurt Asle Arvesen, suffered the same injury at last month's Tour of Qatar and will return to action on Wednesday.
Team Sky's sports director, Marcus Ljungqvist said: "Peter is a strong little guy and I'm sure he'll make a quick recovery."
"It's bad news but, as Kurt has shown, you can come back quickly from an injury like this and Peter will."
