Van Baarle crashed hard after the finish of Thursday’s stage 12, moments after crossing the line in second place.
The Dutchman put in a valiant effort to complete Friday’s 13th stage but his pain and discomfort increased throughout the day and overnight.
Team Sky Doctor Neil Heron confirmed: “Dylan feels very stiff and uncomfortable this morning following his crash on stage 12 and is too uncomfortable to start the stage today. He has been sent for some further imaging which will give us more information.
“We think he has a haematoma within the muscle after the crash – so a bad bruise after he got hit in his groin with the handlebars. Because that was uncomfortable on yesterday’s stage he was compensating with his buttock, which is why he’s getting a lot of muscle spasms in that area.”
Naturally disappointed to leave the race, Van Baarle has already turned his attention to his recovery. He told TeamSky.com: “I was hoping that with treatment it would feel better overnight but the pain has stayed the same. It is a struggle to walk and there’s no point going through another stage in this condition.
“It’s disappointing but I’m trying not to think about it too much. I’m just focussed on getting better again, recovering and taking care of myself. Luckily I’m in good hands on this team and they can help me get better soon. For now I think a day off the bike will help. Good luck to the team for the rest of the race, and also thank you to the fans for all their support and nice wishes after the crash.”
