Tavis made one RWC 2011 appearance, starting in the 81-7 win over Namibia. He was picked for the World Cup squad after being voted man of the match in the pre-World Cup warm-up game against Argentina.
Knoyle had moved up the pecking order of Welsh scrum-halves in 2009/10, earning himself a call-up to tour New Zealand in the summer of 2010. His reward was a first cap as a replacement in the opening international in Dunedin just three weeks after his 20th birthday.
A product of Glynneath, he won four Wales Under 20 caps in 2009 having previously played for Wales at Under 16 and Under 18 levels.
After coming through the ranks at Glynneath, he launched his senior career with Neath and made his Magners League debut for the Ospreys in April 2009, before switching to the Scarlets at the start of the 2009/10 campaign.
He made his sevens debut in the penultimate round of the 2012/13 round of the HSBC Sevens world series.
