Ross Wardle, Jack Dixon and Dan Way have extended their contracts with Newport Gwent Dragons.
Centres Wardle and Dixon and prop Way have signed deals until 2017.
"All these players have potential and now have an opportunity to show consistency and improve on their skills this season," Dragons boss Lyn Jones said.

Jones added: "My target is to dramatically increase our current contribution by the end of my tenure here."
