Scrum-half Cathal Sheridan and props James Cronin and John Ryan have all signed new two-year contracts with Munster and the IRFU, which will see them remain with the province up until June 2016 at least.
The trio have all broken into the first-team set-up this season after graduating from the Munster academy.
Sheridan and Ryan are both part of the squad for tonight's game at Ravenhill.
