Les Kiss does spot of juggling

The Guinness PRO12 table-toppers have re-jigged their back-line with scrum-half Paul Marshall getting a rare start. Charles Piutau moves to full-back with Jared Payne joining Darren Cave in midfield.
Up front, Ireland captain Rory Best gets his first start of the season while Kyle McCall wears the number one jersey. Ireland star Tommy Bowe is likely to get his first run-out for five months having been named on a very strong replacement bench.
