Huddersfield Town duo Joe Wright and Jake Charles are in the Wales Under 21 squad for the 2017 European Championships qualifier in Denmark on Friday, October 9.
Wales have won both their Group 5 games so far, beating Bulgaria and Luxembourg 3-1 in each case.
Defender Wright, currently on loan at Accrington Stanley, featured in both games, in Cardiff and Esch-sur-Alzette respectively.
An injury ruled Charles out against Bulgaria, but the forward made his Under 21 debut against Luxembourg.
The game against Denmark, who have yet to open their qualifying campaign, is in Aalborg.
Wales will also face Romania and Armenia home and away.
The nine group winners qualify for the 12-team finals and the four best runners-up advance to play-offs, from which two win through.
Poland automatically make the tournament as hosts.
