Scott Andrews and Josh Navidi have signed new contracts with RaboDirect PRO12 side Cardiff Blues.
Prop Andrews, who made his Wales debut in 2011, has signed a two-year deal and back-row forward Navidi has committed his future to the Arms Park club until 2016.
Navidi has been one of the Blues' stand-out players this season and skippered them to victory over Munster in Cork last weekend.
He said: "I'm happy with my form at the Blues and feel my playing has been consistent, but I can always keep pushing myself to see how I can improve as a player.
"I don't think about being called up for Wales. I just get on with what I do each week and see what happens from there.
"Changing between six and seven doesn't really worry me, as long as I am on the pitch and representing the Blues. I see a lot more of the ball in the breakdown when I play at seven but then playing at six alongside Sam Warburton is great for my overall game."
Andrews added: "We have had a tough start to the season but we have a great group of boys here and things are looking good for the future, so I am really glad to stay on.
"I have been here since I was 16 and didn't want to look elsewhere as I am happy at the Blues.
"We have a lot of young boys mixed with some top internationals who are contracted for the next few years, so slowly we are producing a good core. It will be exciting to see it progress over the next few years."
