Leinster and Ulster in Heineken Cup action tonight

Leinster and Ulster will both be looking for victories tonight in the Heineken Cup.

Brian O'Driscoll will start for Leinster in their meeting with Edinburgh at the RDS, despite picking up a foot injury last weekend.

Keith Gleeson also replaces Shane Jennings in the back-row, where he will line out alongside Stephen Keogh and Jamie Heaslip.

Bryn Cunningham and Paul Steinmetz, meanwhile, return to the starting line-up for Ulster's visit to the Ospreys.

The Northern province have already lost their opening two games and will be looking to reverse the trend in Swansea.

Elsewhere, Connacht will field an unchanged side at the Sportsground for their Challenge Cup clash with the Newcastle Falcons.
