Dummett, Newcastle United defender, decided to not play for Wales.
He still hasn’t played in a competitive international, but has won two caps, in friendly matches against the Netherlands.
“He doesn’t want to play international football, which is a disappointment from our point of view,” said Wales manager Chris Coleman. “But he’s made that decision, and we have to abide by that.”
Wales are standing third in World Cup qualifying group D, just four points behind the leader, Serbia.
Paul Dummett was born in Newcastle. He was a part of a pre-Euro 2016 training camp but was not chosen in the squad in France and not featured at all during the current World Cup qualifying campaign.
“Sometimes you have to be patient especially because the team we have at the moment has been hugely successful,” Coleman added.
“I was disappointed, but if he doesn’t want to persevere with it then that’s his choice. We’ve got to look after the players who want to play for us”.
