Both men sustained concussions in Saturday night's Pro12 defeat of Glasgow Warriors, and will follow return to play protocols this week

James Cronin requires a scan for a knee injury he picked up at Irish Independent Park, and CJ Stander is another worry; he damaged his ankle in the quarter-final win against Toulouse and could struggle to be ready for the Aviva Stadium collision next Saturday week.

After Saturday’s hardfought win, the squad reassembled in the High Performance Centre at UL as preparations began for the visit of Ulster this Saturday.

Conor Murray (shoulder) continues to be monitored by the medical team.

In better news for the province, Ian Keatley is expected to take a full part in training at some stage this week.

Keatley damaged knee ligaments in last month's victory against Cardiff Blues.

Munster will take on the reigning champions Saracens at the Aviva for a place in this year’s European showpiece.
