The crash happend 3.2 kilometres from the finish line in Jesolo. Both Richie Porte (Sky) and his team-mate, Leopold König, were brought down in a pile-up on a day that turned the general classification on its head.
With riders and bikes strewn across the wet road, Porte was forced to grab a bike from Sky's Vasil Kiryienka and ride to the finish. He lost two minutes and eight seconds to the lead peloton. König crossed the line just seven seconds in front of Porte, also falling out of the top 10 overall.
Race leader Alberto Contador (Tinkoff-Saxo) was another victim of the crash was forced to relinquish the maglia rosa on what had looked, on paper, like a straightforward sprint stage.
Porte, who was penalised two minutes earlier this week after Simon Clarke (Orica-GreenEDGE) loaned him a wheel, now sits in 17th overall. He is five minutes and five seconds back on new race leader Fabio Aru (Astana).
“Richie lost more time today after the crash and it’s certainly not a lucky Giro d’Italia for him," said team-mate Elia Viviani, who sprinted to third in the stage. "Tomorrow we have a big time trial and then after the Madonna di Campiglio stage he can decide what he wants to do for the rest of the race.
“We knew it was dangerous today with the rain and we had a lot of guys to support Richie. But there was another crash and it’s just not a lucky race for us.”
"The guys were well-positioned in the peloton when the crash happened. There wasn’t much that we could do," said Sky's Sports Director, Dario Cioni.
"Let’s see how it goes tomorrow with the time trial. It’s a huge test and after the outcome of that we’ll see where we are and make a plan."
