Adam Jones played in all of Wales' 2014 RBS 6 Nations games
Wales prop Adam Jones admits he is relishing the chance to get to grips with a new challenge after joining Cardiff Blues.
Front row Jones, who has made 95 appearances for Wales since making his debut against England in 2003, left Ospreys at the end of last season.
The destructive prop has been a cornerstone of the Welsh pack for the last decade, scoring on his first RBS 6 Nations appearance against Scotland in 2004.
Since then Jones has won three Grand Slams with Wales in 2005, 2008, and 2012 and featured in all five of his country's RBS 6 Nations matches this year.
The British and Irish Lion has signed a one-year deal with the Blues after 11 years with the Ospreys.
"This is about a new challenge for me," he said. "At this stage in my career I want a new environment and to really push myself.
"I've been really impressed by the set-up at Blues and the desire to achieve in the coming years under the leadership of Mark Hammett. It is that ambition and potential for the future that excites me about this move.
"Obviously I would like to thank everyone at the Ospreys - from the players and coaches to the wonderful supporters - who have been absolutely fantastic with me. I wish the region every success for the future."
Wales' acting head coach Rob Howley has given Sam Davies and Rory Thornton a boost ahead of the RBS 6 Nations by naming the uncapped Ospreys duo in his largely experienced squad for the Autumn Internationals.
England's preparations for the Autumn International series were potentially dealt a further blow as Maro Itoje was forced to undergo an x-ray after Saracens' European victory over Scarlets on Saturday night.
