The Welshman picked up the injury to the bone in his right wrist during the European Championships road race after his hand hit a barrier.
Rowe finished 15th on the day and was subsequently also able to complete the Deutschland Tour, yet felt increased pain during the race. After seeing a specialist in Cardiff a scan revealed the fracture, which will require the Team Sky rider to be in plaster for six to eight weeks.
“I got the injury back at the Euros going into the last lap. It was just a racing incident really – it wasn’t anyone’s fault,” Rowe told TeamSky.com. “I clipped my right hand on a barrier on a right-hand bend. I got a small cut on my hand, and at the time it was quite sore, but I just got on with it.
“I did a Roubaix recon on the Tuesday before Deutschland Tour and then throughout that race, and certainly in the last few days, I was in quite a bit of pain. I was trying to tape the wrist but every time I hit a pothole or speed bump it was getting painful, so that’s when I thought I better get a scan.
“All I had left on my race programme was Canada so there’s no chance I’ll be able to race there which is a shame. I’m going to be in a plaster cast for six to eight weeks to give myself the best chance for it to heal.”
