Leinster will be without their captain Johnny Sexton for Sunday's trip to La Rochelle in the Heineken Champions Cup semi-finals. 

The former world player of the year hasn't played since suffering a head injury in the Blues' victory at Exeter earlier this month and the PRO14 champion say he'll continue to go through the return to play protocols.

A decision on Caelan Doris' fitness will be made later in the week, he was a late withdrawal with a calf issue ahead of Leinster's loss to Munster at the weekend.

"It would have been good to get him any game time really, just to see where he's at but, again, we'll see how he turns that calf around," Leo Cullen saoid after the game at the RDS.

"He's trained over the last number of weeks which is the positive piece. He was raring to go so that's just the way it played out."

James Ryan, Garry Ringrose, Scott Penny and Tommy O’Brien came through the Munster match with no issues while Ciarán Frawley and Harry Byrne are nursing hamstring niggles.

Ireland scrum-half Jamison Gibson-Park also has a slight hamstring issue and he'll be assessed throughout the week.
