Trebanos-born Justin Tipuric made his Wales debut against Argentina in August for the pre-World Cup warm-up fixture, before gaining his second against Australia at the Millennium Stadium as a replacement against Australia.
He has been with the Ospreys since U16 level and 2010/12 saw him break through with 27 appearances and two tries, including a fine individual effort against Edinburgh.
Tipuric, whose grandfather is Croatian, has represented Wales at every age-grade level and he was hugely successful at Under 20 level, making 18 appearances over two seasons and scoring eight tries, six of which came at the 2009 Junior World Championship in Japan.
Tipuric also starred for the Wales Sevens squad in 2009/10. He has plenty of experience at Principality Premiership level, playing over 40 times for Aberavon.
