Foley and Costello just need to run the rule over those players who picked up niggly injuries in both AIB and Magners League matches at the weekend before deciding on the match day squad. Munster currently lie second in the table, one point behind Bristol but know that if they finish level with the English side, they'll advance to the semi final by virtue of their win in Nenagh RFC.

Included in the 27 strong squad are Ian Nagle, Billy Holland, Nick Williams, Duncan Williams and Scott Deasy who were all involved in the Munster Magners League squad last weekend in Newport.

Munster Squad (v Heriots): Dave Kilcoyne, Stephen Archer, Pa O'Regan, Sean Henry, Mike Sherry, Dave Foley, Ian Nagle, Sean Duggan, Ed Kelly, Billy Holland, Neville Melbourne, Peter O'Mahony, Shane Hassett, Nick Williams, Duncan Williams, Conor Murray, Declan Cusack, Andrew Burke, Jeremy Manning, Ciaran O'Boyle, Danny Barnes, Sean Scanlon, Ronan O'Mahony, Scott Deasy, Eric Maloney, Danny Riordan, Mike Kelliher.
