Duncan Jones has represented Wales at Schools, U18, U19, Youth and U21 levels, playing a key part in the U21 Grand Slam side of 1999, and has also played for Wales A and the Wales Development XV. He made his senior debut for Wales as a replacement against Australia in 2001.
Jones was a key figure in the 2003 Rugby World Cup squad until he broke his ankle against Italy. After fighting back to fitness he played in the 2004 Lloyds TSB Autumn Series, but missed the 2005 RBS Six Nations Grand Slam campaign due to a dislocated thumb.
Domestically, Jones played for Neath RFC before moving into the regionalised Ospreys squad in 2004. He made 22 appearances for the region during the 2006–2007 season, successfully captaining the side to the Magners League title.
Jones won the Welsh Rugby Writers' Association's Player of the Season award in May 2006, and his inspiring form throughout 2006 gained him the captaincy of the youthful Wales squad destined for the tour of Argentina. Additionally, he was named as replacement captain, as a stand-in for the injured Stephen Jones, to face the Pacific Islanders in the 2006 Invesco Perpetual Series. Jones also starred in the three other games of the Series against Australia, Canada and New Zealand.
Jones appeared in every game of the 2007 RBS Six Nations and in June was named in Gareth Jenkins's 41-man preliminary Rugby World Cup 2007 summer training squad, having been rested from the squad that toured Australia in May. He was selected as part of the final 30-man RWC squad in August and played in both Invesco Perpetual Summer Series matches against Argentina and France.
Jones made substitute appearances in three of Wales's Pool B encounters at the 2007 Rugby World Cup, and made the starting line-up at the Millennium Stadium against Japan. In November he was included by Caretaker Coach Nigel Davies in the 22 to face world champions South Africa in the initial Prince William Cup match at the Millennium Stadium; Jones came on as a replacement in Wales's defeat.
The prop was selected to start against England and Scotland in the 2008 RBS Six Nations after being included in Warren Gatland's 28 man squad; he also featured in the three other matches as a replacement for Gethin Jenkins, and won his fiftieth cap in the championship decider against France at the Millennium Stadium.
