In the full Wales squad are Daniel Gabbidon, Rhys Weston and Robert Earnshaw. Danny is likely to start against the Serbs at the Millennium Stadium on Saturday night while Earnie and Rhys should be on the bench.
Neil Alexander will be on the bench for Scotland as they play Lithuania at Hampden Park.
Graham Kavanagh could be a surprise starter for Ireland against Switzerland. Kav has been recalled for the Republic after a 4 year absence.
Good luck to all the players and let's hope they have a successful injury free weekend.
Cardiff's next action is away at Sunderland next Tuesday, October 14th, ko 7:45pm.
