Team news:  Brian O'Driscoll is deemed fit and will start for Leinster in the Magners Celtic League clash against  the Ospreys at the RDS tomorrow night.

The Leinster and Ireland captain missed last week's 29-0 trouncing of Ulster and returns to partner Felipe Contepomi at centre with Jonathan Sexton continuing at outhalf after impressing in last week's win at the RDS.

Sexton will be partnered by Chris Keane at scrumhalf while the other change in the backline sees Gary Brown start on the right wing in place of Rob Kearney, who picked up a slight knock in training during the week.

In the pack, Brian Blaney starts at hooker and lines up alongside Cian Healy and Stan Wright in the frontrow. Cameron Jowitt partners Malcolm O'Kelly in the secondrow, while Shane Jennings starts in the backrow alongside Stephen Keogh and Jamie Heaslip.

Gordon D'Arcy is one of five Irish internationals named on the bench alongside Guy Easterby, Keith Gleeson, Bernard Jackman and Trevor Hogan, who returns to the squad for the first time since suffering a knee injury three months ago.

Tomorrow's game kicks-off at 7.30pm as the league leaders take on midtable opponents who have shown form of late.

"We were delighted with our performance against the Blues and to have restricted a team of their quality to only three points is something we can be proud of," said head coach Lyn Jones

"This has been an extremely challenging holiday period for our players and although it has brought the best out them we had a lot of bruised and battered bodies reporting for training this week.

"We are continuing to build as the season progresses and we hope to continue to progress this weekend. This will be our first visit to the RDS and we fly out to Dublin in confident mood gained from our good form over the last few months," added the Ospreys coach.
