Pro 12 Team News: Leinster have made eight personnel changes and one positional to the side that beat Benetton Treviso last weekend ahead of their Pro 12 meeting with Cardiff Blues at the RDS tomorrow (8.05pm).
In the backline Luke Fitzgerald makes way for the return of fullback Isa Nacewa, while Fergus McFadden moves from the wing to inside centre as Gordon D’Arcy makes way for Dave Kearney.
McFadden, who boasted a 100 per cent kicking record against Treviso, will operate alongside form-man Eoin O’Malley, while in the halfbacks Ian Madigan is retained but will be partnered by Isaac Boss instead of Eoin Reddan.
The pack sees the return of captain Leo Cullen who, along with Steven Sykes, replace locks Damien Browne and Devin Toner. In the frontrow, Richardt Strauss and Nathan white are called upon to work with Cian Healy, while Seán O’Brien replaces former Old Belvedere number eight Leo Auva’a.
