Joe Ledley started Wales' match in Dublin against the Republic of Ireland but was substituted at half time. Paul Parry did not get a cap as the Welsh went down to a disappointing 1 - 0 defeat.
Warren Feeney played for over 30 mins after coming on as a sub for Northern Ireland in Liechtenstein. The Irish won 4 - 1.
Neil Alexander was an unused sub as Scotland secured a last gasp win over Georgia at Hampden Park, 2 - 1.
On Wednesday night the countries are all in action again.
Wales face San Marino at the Millennium Stadium, Northern Ireland are at home to Sweden and Scotland are away to Italy.
Good luck to the lads and let's hope they all return on Thursday, injury free.
