“I’ve a couple of things to come through. I’ll see how the week goes.”

Head coach Johann van Graan added:

“(O’Mahony) won’t train today. He could possibly play at the weekend. We’ll manage him through the week and we’ll see in two days’ time if he’s able to train.

“I’m hopeful he’ll be captain on Sunday and lead us out at Thomond Park.”
