The Dragons have confirmed that Lyn Jones will be their new director of rugby.
The 49-year-old left his position as head coach of London Welsh last week, saying he wanted to return to Wales to be closer to his family.
He has previously coached the Ospreys, and worked as a consultant with the Dragons in 2009.
Darren Edwards will stay at Rodney Parade as head coach, with Robert Beale moving from rugby director to team manager.
Dragons chairman Martyn Hazell said: "Last season was a difficult one for us at the region, but having brought our finances under control, we are looking to build our team for the future."
"With some key signings made during the off-season, we are confident that Lyn has the experience and expertise to support our coaching team and ensure that we get the very best out of our group of young, talented players."
London Welsh are facing relegation from the Aviva Premiership after losing 14-31 to Northampton - their 10th successive league defeat - leaving them at the bottom of the table. Their only hope of survival is if the Championship title winners do not meet Premiership entry criteria.
The defeat follows reports that the club's majority shareholder Kelvin Bryon intends to pull out of the club claiming he had "had enough" of Premiership Rugby and the Rugby Football Union.
The independent Appeal Panel accepts that the circumstances of this case are quite exceptional. However, we have to mark this serious breach with a points deduction and, although we have allowed the appeal in respect of the five points which were suspended, we must acknowledge the impact on the integrity of the game and deduct five Premiership points with immediate effect.
– Gareth Rees QC, Chairman of the Independent Appeal Panel
London Welsh say they are "extremely disappointed by the Independent Appeal Panel’s decision" to uphold the five-point deduction and £15,000 fine against the club, for fielded an ineligible player, Tyson Keats, in ten Aviva Premiership matches this season.
The decision means that the club remain five points adrift at the bottom of the Aviva Premiership.
In a statement London Welsh said that the RFU's decision to remove the additional suspended five-point penalty imposed until the end of the 2013-14 season, justified their decision to appeal.
The club is hugely disappointed by the decision of the Independent Appeal Panel to uphold the five-point deduction for this season.
We are particularly disappointed for the players, who’ve given everything they can for the club, and ultimately it is they who have been punished for something completely beyond their control.
However, there are still four games remaining in the season and the focus and efforts of the players, the coaching staff and everyone at London Welsh is now on those remaining matches.
London Welsh have confirmed they'll appeal a decision to deduct the club ten league points and fine it £15,000 over the fielding of an ineligible player.
In a statement this evening, the club calls the decision 'extremely harsh under the circumstances'.
The club was unknowingly the victim of one individual’s fraudulent conduct and it was London Welsh which discovered the fraud and brought it to the attention of the RFU. The Panel however has punished London Welsh on the basis that it is to blame for what that individual has done.
London Welsh are hugely disappointed and shocked by the ruling made by the RFU Hearings Committee, which we believe is extremely harsh under the circumstances
On the rugby field, London Welsh have succeeded in their quest for a place in the Aviva Premiership - even if their chances of success off the pitch are still slim. They beat Cornish Pirates 29-20 last night, to secure a 66-41 aggregate victory in the Championship play-off final.
Their promotion to the top flight has been blocked by the RFU because of issues around not having tenure at their nominated ground - Oxford United's Kassam Stadium. The club has said it plans to appeal that decision, chairman Bleddyn Phillips saying they would do "everything within our power."
The Rugby Football Union's board of directors have ruled that London Welsh have failed to meet the minimum standards criteria set for a place in the Aviva Premiership.
The team are not eligible for promotion after the report, carried out by independent auditors, identified various failures which involved not having tenure at their nominated Premiership ground - Oxford United's Kassam Stadium.
The RFU verdict was announced just six hours before London Welsh contest tonight's Championship final first leg against Cornish Pirates in Penzance, and means that Premiership bottom club Newcastle will retain their top-flight status next term subject to any successful London Welsh appeal.
a club must demonstrate that they can host home fixtures at the time stipulated by Premiership Rugby and/or the host broadcaster...The RFU board agreed, should London Welsh win the RFU Championship final following the second leg on May 30, they would not be eligible for promotion and Newcastle Falcons would remain in the Aviva Premiership.
London Welsh have the right to appeal and would be required to do so within 14 days of this decision.
