WATCH: Isaac Boss determined to make the most of his chance to shine

Isaac Boss knows he faces a battle for a place in Joe Schmidt's final 31-man World Cup squad, and is ready to take his chance to impress this afternoon.

The Leinster player starts at scrum-half against Scotland in the Aviva Stadium, having seen provincial teammate Eoin Reddan start in the position last week, and Kieran Marmion impress when he came off the bench.
