Fergus McFadden is one of five changes in Leinster’s line-up as the champions welcome Ulster to the RDS tomorrow.

The centre hasn’t played since he had surgery on a thumb injury after the game against the Ospreys in late November.

Captain Jamie Heaslip returns, while head coach Matt O’Connor starts Jack McGrath and Mike Ross in the front row for the Guinness PRO12 tie.

Devin Toner comes back into the second row to partner Mike McCarthy, while in the back row Heaslip starts at eight so Jack Conan moves to blindside flanker.

LEINSTER (v Ulster): Z Kirchner; F McFadden, L Fitzgerald, G D'Arcy, D Kearney; I Madigan, I Boss; J McGrath, R Strauss, M Ross, D Toner, M McCarthy, J Conan, S Jennings, J Heaslip (c). Replacements: S Cronin, M Bent, T Furlong, K Douglas, J Murphy, L McGrath, J Gopperth, B Te'o.
