McGahan shuffles backline

Munster retain the same pack of forwards that played against Castres in round two of the Heineken Cup for the clash with Pool leaders Scarlets in Parc Y Scarlets tomorrow (3.40pm).

There are four changes in the backline, one necessitated by the injury to Doug Howlett with Simon Zebo coming into the side despite an injury scare earlier in the week when he hurt his ankle. Zebo will be making his Heineken Cup debut on the day that Ronan O'Gara becomes only the second player, after John Hayes, to win 100 Heineken Cup caps.
