"Geraint has a proven track record for Pontypool and his level of experience and game time should enable him to step up to regional level.
The return of centre Ashley Smith will boost the Dragons backs as the Men of Gwent look to secure their first victory in Galway since 2004.
"Having Ashley Smith back is obviously great for us and I trust that our players are good enough to pull off a strong performance despite the fact that there will be a couple of newer faces and a few players out of position."
