Leinster will be without Adam Byrne for the rest of the season. The winger's campaign has been ended by a quad injury picked up in their recent defeat to Glasgow.
Sean Cronin will sit out the Blues' trip to Ulster in the Guinness Pro14 this Saturday with a calf injury but the province haven't put a timeline on his recovery.
Scrum-coach John Fogarty admits the hooker is a doubt for their Heineken Champions Cup decider against Saracens next month.
“We’re not quite sure how he’s going to pan out. He’s a pretty important player for us, but we have some time. Us doing so well in the Pro14 gives us next week to get people back and prep and train.
“Seán will need it to get himself back but we won’t know for sure just yet. It’s working out when he’ll get back, and we’re not quite there yet. He’ll be assessed and monitored and then there will be markers this week he has to hit. To say he’ll be back and flying it wouldn’t be truthful.
“At this moment in time, he can’t train or play. Hopefully, he’ll do a small bit of running later in the week but he’s getting assessed now. Right now, he’s a concern.”
Rhys Ruddock is following the return-to-play protocols after feeling unwell after the captain's run ahead of last weekend's victory over Toulouse and Fogarty says they weren't going to risk the flanker.
“In a game like that semi-final, we need to make sure everyone is 100% so they can commit hard to it, Rhys didn’t feel quite right so they pulled him. That’s pretty much it, he wasn’t 100%. They’re going to assess him again this week.”
Prop Andrew Porter and scrum-half Jamison Gibson-Park are doubts for this weekend with pectoral and hamstring injuries respectively.
