Leinster make four changes while Ulster stick with winning side

200 not out for the number 8.

Captain Jamie Heaslip will lead out Leinster to mark his double century of appearances for the province, as Matt O'Connor makes four changes for tomorrow night's trip to Kingspan Stadium to face Ulster. There are two changes each in the back and forward lines, with Leinster needing a win to keep alive any hopes of making it into the Pro 12 semi-finals. In the pack, Richardt Strauss comes in to start at hooker with Sean Cronin on the bench, while Dominic Ryan is given a chance to impress in the backrow, with Jordi Murphy a substitute. Gordon D'Arcy links up with Ben Te'o in the centre, while the final changed sees Zane Kirchner start on the right wing, after Fergus McFadden's season was ended with a fractured thumb against Toulon on Sunday. Meanwhile, Ulster head-coach Neil Doak has stuck with the same XV that recorded a bonus point win against Connacht last time out, with Chris Henry continuing his comeback in the backrow. The strong Ulster side sees four of Ireland's 2015 Six Nations Winners start, Rory Best and Iain Henderson in the pack, and Tommy Bowe and Jared Payne in the backline.
