French-based professional James McLaughlin has pulled out of Guernsey's Island Games cycling team.
The 22 year-old is needed by his Sojasun-Espoir team for a stage race straight after the event in Bermuda.
"Coming from the other side of the world he doesn't want to leave it until the last minute to get back and then hit a stage race," said Guernsey Velo Club president Gary Wallbridge.
Phil Touzeau, has been selected to replace McLaughlin in July.
"Ten days out in Bermuda is not the best preparation for his stage race the following week," Wallbridge added to BBC Guernsey.
"Due to his commitments with his French team he has reluctantly had to back out."
But Wallbridge says it is a good opportunity for Touzeau, who was a reserve rider in 2011.
"Phil narrowly missed out on the Isle of Wight two years ago so he knows what it's like to not be selected."
But Guernsey's other professional rider, Tobyn Horton, will race for the island after being given clearance to compete by his UK Youth team.
