Leinster boss Leo Cullen has hailed Caelan Doris' "very unique" qualities after picking him to start in the number 7 jersey for the first time for Friday night's Champions Cup quarter-final clash with Leicester Tigers.
Doris, 24, has played at no 6 and no 8 in the back row for Leinster and Ireland, and has been most effective at no 8.
But with reigning world player of the year Josh van der Flier missing out with an ankle injury, the Blues brain trust had a choice to make and Doris, who missed out on the last 16 victory over Ulster through illness, gets the nod over in-form Scott Penny for the openside slot - and with Ryan Baird and Jack Conan hold down their places alongside side him.
