Guernsey will be without influential all-rounder Lee Savident for their World Cricket league Division Five tournament campaign next month.
Former Hampshire player Savident needs an operation on his back after suffering a slipped disc.
"Lee is desperately disappointed to be missing the tournament and given his contributions to the team he will be missed," said coach Andy Cornford.
"But we look forward to having him back injury free in the future."
All-rounder Tim Duke comes into the squad in place of Savident while fellow all-rounders William Peatfield and Matthew Renouf are also brought in for Chris Van Vliet and Adam Martel for the trip to Singapore.
"The three all-rounders all bowl seam, which is an area we wanted to bolster," Cornford added.
"We're all excited about World Cricket League 5 and returning to Singapore and whilst recognising the challenges ahead, we're confident that we can build on our performances from Malaysia."
Guernsey will face the Cayman Islands, Argentina, Bahrain, Singapore and Malaysia in the tournament which runs from 18-25 February.
"World Cricket League Division 5 provides us with our second huge challenge in 6 months," said team manager Pete Vidamour.
"As we progress up the leagues the standard of opposition will, of course, get better and our squad will undoubtedly face a number of tough matches in Singapore.
"We need to build on our success in Malaysia and we're confident that this squad has the talent and commitment to at least consolidate our current position."
