Charlie Irvine suffered a calf muscle injury in Friday's defeat to Leinster and has been ruled out of this week's fixture.

Nathan Doak (calf), Rob Baloucoune (shoulder) and Stewart Moore (wrist) are all injury concerns.

Cormac Izuchukwu and James Hume, who were both ruled out of the Leinster fixture due to illness, have returned to full team training and are fit for selection.
