Right-back Elliott Hewitt is the only senior Town player away on international duty this week. The 19-year-old is with the Wales U21s ahead of their Euro 2015 qualifier against Finland at Bangor City’s Book People Stadium on Wednesday (4pm).
Hewitt has previously won six caps with the U21s, who are coached by former Blues midfielder Geraint Williams.
Meanwhile, ex-Town keeper Cody Cropper has been named in the full US squad for their friendly against Bosnia-Herzegovina in Sarajevo on Wednesday.
The 20-year-old, who is unlikely to play with Tim Howard and Brad Guzan also included, came through the Town academy and was on the first-team bench on a number of occasions without making an appearance before being released in the summer of 2012.
He subsequently joined Southampton on a two-year professional contract after a trial and was a regular in their U21s last season but is yet to break into their senior side.
Wales U21s: Connor Roberts (Cheltenham Town), Danny Ward (Liverpool), Daniel Alfei (Swansea City), Lee Evans (Wolverhampton Wanderers), Morgan Fox (Charlton Athletic), Kieron Freeman (Derby County), Elliott Hewitt (Ipswich Town), Scott Tancock (Swansea City), Joe Walsh (Crawley Town), Billy Bodin (Torquay United), Chris Dawson (Leeds United), Emyr Huws (Manchester City), Lloyd Isgrove (Southampton), Lee Lucas (Swansea City), Wes Burns (Bristol City), Jake Cassidy (Wolverhampton Wanderers), Ellis Harrison (Bristol Rovers), Tom Lawrence (Manchester United).
