Paul Turner said: "This week Anthony and Alex were brought into the squad. It's a great environment to stake a claim for being a professional and, having talked to both of them, they definitely won't let us down.
"Lloyd Burns also has a great opportunity tomorrow evening and as he's been training with us this season it's great to see."
Dragons Rugby Manager Robert Beale commented: "I'm really grateful for the support from Head Coaches Sven Cronk of Newport RFC and Will Thomas of Ebbw Vale for releasing Alex and Anthony on the eve of what is a very important game for both clubs in the Principality Premiership game at Eugene Park."
He added: "It's a great opportunity for both to come to Rodney Parade and experience professional rugby which I'm sure will benefit both their clubs going forward."
