Richie Porte says he is “gutted” to be out of the Giro d’Italia due to injury following what can only be described as a nightmare week for the Team Sky rider, who began as one of the pre-race favourites.

Team Sky said this morning that medical staff had advised the 30-year-old Tasmanian to withdraw. He will now focus on getting fit to support Chris Froome at July’s Tour de France.

This time last week, Porte sat in third place overall but his challenge began to unravel on Tuesday, when he accepted a wheel from Orica-GreenEdge’s Simon Clarke following a late puncture.

He was docked 2 minutes for accepting illegal assistance and also lost 47 seconds on the road.

Porte was then caught up in the crash near the end of Friday’s Stage 13 at Lido di Jesolo, injuring his knee and hip and losing more time.

He was off the pace on Saturday’s individual time trial, and lost more than 27 minutes on yesterday’s stage to Madonna di Campiglio.

Porte told the Team Sky website: “The Giro has been my main goal this year and I’ve worked incredibly hard all season with this race in mind.

“I’ve had a lot of back luck this week with the puncture and the time penalty, but it was the crash on Friday that has taken its toll.

“I fell heavily on my knee and hip which caused me a lot of pain on Saturday’s time trail and yesterday’s stage.

“I just wanted to keep trying and give it everything but now the medical team have advised me not to continue.

“I'm gutted it’s ended this way and that I can’t stay and support Leo [König], Elia [Viviani] and the team in the last week.

“They’ve been outstanding every step of the way and to not be able to repay that is tough.

“The plan for me now is to take some time off the bike, get the medical treatment that I need and reset my goals for the rest of the season and come back fighting.

“Hopefully I can get myself ready for the Tour team,” he added.

Today is the second rest day of the Giro, with the race led by Alberto Contdaor of Tinkoff-Saxo by 2 minutes 35 seconds from Astana's Fabio Aru.

Racing resumes tomorrow with a daunting stage from Pinzolo to Aprica, including the climbs of the Tonale and the Mortirolo.
