Leinster rule out Ciarán Frawley for Cardiff but Jack Boyle and Jimmy O'Brien return

Ciarán Frawley won't be available for Leinster this weekend, but fellow Ireland internationals Jack Boyle and Jimmy O’Brien trained with the team on Monday afternoon.

Out-half Frawley was replaced after 55 minutes of Ireland A's defeat to England A in Bristol on Sunday after suffering a head injury.

Frawley, who has eight Ireland caps, has yet to feature in the Guinness Six Nations after three rounds.

"He hasn’t been back in the building today but I think he’s fairly good," assistant coach Tyler Bleyendaal told RTÉ Sport ahead of Saturday’s meeting with Cardiff in Aviva Stadium (3pm, live on RTÉ2 and RTÉ Player).

"He’s recovering well but I’m not sure where he’s at in terms of the return to play protocols.

"He won’t be available for us this weekend."

Ireland winger O’Brien, who also hasn’t played in the Six Nations so far, and prop Boyle (below), who made his Ireland debut in the win over Wales, were pictured training with Leinster earlier today.

"Boyler’s a great character and we’re all really pleased to see him get his cap over in Wales," added the New Zealander.

"You might have seen the song he sung after the game. He’s a good character, the guys love him, he brings a good energy but does the job on the field.

"We’re really excited, hopefully he gets back playing with us shortly. It’s great to see him in the Irish colours doing really well."

Tommy O’Brien, Max Deegan, Stephen Smyth, Paddy McCarthy, Conor O’Tighearnaigh, Alex Soroka and Fintan Gunne were also in action in Bristol on Sunday with Bleyendaal adding "most of the other [A] guys are back in the building, looking excited and energised to be back with Leinster."

Meanwhile, Leinster out-half Harry Byrne (above), who is on a short-term loan deal with Bristol Bears, also
