Three Baggies were in action for their nations on what was a busy night of action on Saturday evening.
Isaac Price, Jayson Molumby and Felix Horn Myhre all featured in UEFA Nations League action, with mixed fortunes on offer.
Price played the entirety of Northern Ireland's crucial 1-0 victory over Ukraine in Belfast.
Terry Devlin's 68th-minute strike earned Michael O'Neill's side the spoils, a result which keeps them top of their group with one fixture left to play.
That game will be up against Callum Styles' Hungary, who themselves earned a 2-0 win over Georgia on Saturday, in which the Baggies defender was an unused substitute.
There was victory too for Horn Myhre, who made a late appearance on his return to the Norway squad against Wales.
The Baggies midfielder came on in the 91st minute, after strikes from Antonio Nusa, Andreas Schjelderup and Erling Haaland gave them a commanding 3-1 lead in Oslo.
David Brooks netted for Craig Bellamy's side, for which Albion defender Chris Mepham was an unused substitute.
Elsewhere, Molumby, Max O'Leary and the Republic of Ireland suffered a 1-0 defeat to Austria.
The Baggies midfielder played the full 90 minutes, with O'Leary an unused substitute in Linz - as Sasa Kalajdzic scored the only goal of the game with just over 10 minutes to play.
Next up for the Republic of Ireland is a crucial clash with Kosovo on Tuesday evening (ko 7.45pm). Norway will take on Denmark on the same night (ko 7.45pm), whilst Wales face a tough encounter with Portugal - also on Tuesday (ko 7.45pm).
