Neither Lewis Price nor Jaime Peters were involved as their international sides fell to defeats on Saturday. Price wasn't named in the Wales 16 which lost 1-0 to England, while Peters was an unused sub in Canada's 2-1 defeat in Spain.
Canada's goal came from former Town trialist Sandro Grande.
Former Blue Darren Bent also failed to make it onto the field but was named amongst Sven-Goran Eriksson's subs at the Millennium Stadium.
Town will receive a six-figure top-up from Charlton if the 21-year-old makes an appearance in a competitive international. Boss Joe Royle will hope his loan budget is boosted by Bent making his full England debut against Northern Ireland at Windsor Park on Wednesday.
