The Orica-GreenEdge posted a photo of his x-ray to Instagram, writing, "That would be why my elbow hurts! Little fracture of the radial head. Couple weeks on the ergo ahead of me now. What doesn't kill makes you stronger."
This year's edition of Strade Bianche was rife with crashes due to high winds that buffeted the peloton. Zdenek Stybar (Etixx-Quickstep) won the race in a sprint against Greg Van Avermaet and Alejandro Valverde in Siena.
Gerrans' compatriot Calvin Watson (Trek) also crashed, stating on Twitter that the wind was the cause.
Ian Stannard (Team Sky), the winner of Omloop Het Nieuwsblad, also crashed out of the race, but according to TeamSky.com he suffered only a bruised knee.
