Hooker Marc Breeze and scrum-half Lewis Jones have signed new deals with Cardiff Blues.
Breeze joined Cardiff from Aberavon RFC in October 2011, and he also had spells with Ospreys and London Welsh.
He said: "When I received the phone call last October to be part of the Cardiff Blues team I could not have asked for more.
"I had played against the boys regularly and played with some of them through the age grades, so I fitted in quite quickly.
"I played twenty-seven games in thirteen months and also played my first Heineken Cup matches with the Cardiff Blues, which has been great for me.
"The facilities at the Blues are the best in Wales. You can't compare them with the ones at some of the other clubs that I have been to."
Lewis-Jones was released by the Blues Academy in November 2010, but he was invited back after impressing for Pontypridd RFC and progressed to the senior side.
"Obviously there is a lot of us coming up through the Blues at the moment and we are getting a lot of experience early on in our careers, which hopefully will benefit us as individuals and also as a squad," he told the club's website.
"It's an exciting time to be involved at the Blues so I'm glad to have signed a contract extension."
