The U21s boss did concede the mistake was a disruption, though denied he was left angry by what had happened.
“There will be a review to get to the bottom of it and make sure it doesn’t happen again,” said Jones, a former Wales, Leeds United and Leicester City midfielder.
“It has caused disruption and unnecessary noise. I think I managed it the best I could but ultimately it’s at the back of your mind and at the back of players’ minds as well.
“We know we have the strength in the squad to cater for players when they’ve been missed, when they’ve been good enough to go up to the first team.
“Of course everyone wants a Rubin Colwill and Owen Beck in the team but we’ve shown before we can manage without them. It wasn’t a major concern, but how it came about was disappointing.
“We will stick together and take the responsibility as a whole. It’s a ‘we’ problem rather than about pointing fingers.”
Jones did admit his emotions were “really fragile” at the prospect of the end of a campaign that had impressed and threatened to create history.
Victory would have given Wales a chance of a first appearance at a major finals at this age grade, last coming close when a side containing the likes of Aaron Ramsey and Joe Allen reached the play-offs in 2008.
Ramsey was in the crowd at Rodney Parade with Wales needing only a point to guarantee a play-off place themselves.
