Munster senior coach Mike Prendergast is optimistic that Jack Crowley, Jean Kleyn and Michael Milne will be available for Saturday’s historic Champions Cup clash with Gloucester at Páirc Uí Chaoimh.

The trio missed last weekend’s defeat in Bath, but they were able to take some part in today’s training session at a storm-hit University of Limerick.
