Cian Healy a doubt for November series with "significant" hamstring injury
Cian Healy has aggravated a hamstring injury which will see him miss the opening two games of the Champions Cup and makes him a doubt for Ireland's November internationals against Georgia, Australia and South Africa.
He has been ruled out for at least four weeks with Matt O'Connor confirming that he suffered a "significant hamstring strain". The prop will be assessed over the coming days to determine the seriousness of the injury.
There was better news for Sean O'Brien who hasn't been selected for the game against Cardiff tomorrow night with O'Connor saying he is not far away from a return after he had a "loosebody" removed from his ankle.
Jack McGrath(calf) and Shane Jennings (hamstring) are also looking at a number of weeks on the sidelines.
Meanwhile, Leinster coach Matt O'Connor has named Australian import Kane Douglas in his starting XV for tomorrow night's clash with the Cardiff Blues at the RDS (kick-off 7.35).
Douglas, who only arrived in Ireland this week, is named in the second row alongside Ireland international Devin Toner.
The team to face Cardiff also sees Gordon D'Arcy named in the starting XV. D'Arcy will play at outside centre in his first start of the season, partnering Ian Madigan in midfield.
Jamie Heaslip will captain Leinster and will be flanked in the back row by Rhys Ruddock and Dominic Ryan, the latter making his fourth successive start of the season.
Marty Moore will start his first game of the season against Cardiff, with Michael Bent and Sean Cronin completing the front eight.
The back three that started in the defeat against Connacht last week are retained for the Friday night match against Cardiff. Darragh Fanning and Fergus McFadden will take their places on the wings, and Rob Kearney will start at full-back.
The half-backs also remain the same, with Eoin Reddan and Jimmy Gopperth both set to start.
