National team coach Chris Coleman alleged that the centre-back turned down the opportunity to join the squad and questioned the player's attitude.
"I was not contacted by Chris Coleman or anyone at the FAW to request I join up with the squad," BBC Sport quotes him as saying. "Had I been asked I would have gladly represented my country."
"I did have a conversation with Chris to try to seek clarification on why I had been left out of the initial squad for both the Macedonia and the Serbia matches - but at no stage did I state that I would refuse to play for Wales," he added.
"I am proud to come from Wales and even prouder to pull on the red shirt of my country so the suggestion that I would ever refuse to play for them is plainly wrong."
Wales lost the match 3-0, a result that saw them sink to the bottom of their qualifying group.
