Jamie Roberts will win his 50th cap for Wales today.
The 6' 4" centre made his debut - on the wing - against Scotland at the start of the 2008 Grand Slam campaign.
He was named as the British and Irish Lions Player of the Series in South Africa in 2009.
Roberts is leaving Cardiff Blues at the end of the season, to play his club rugby in France.
Roberts, and centre partner Jonathan Davies, will take on the recalled French wrecking-ball Mathieu Bastareaud today.
Davies said: "Obviously, he (Bastareaud) is very physical and strong. Our defence will be key to cut his time on the ball and slow him down before he gets going. Hopefully, we can get a result for Jamie to celebrate his 50th cap."
