Montpellier have added the former Munster and Ireland scrumhalf Tomas O'Leary to their Champions Cup roster ahead of Sunday's Champions Cup match against Leinster.

The 32-year-old scrumhalf wasn’t listed in Munster’s playing squad for the European competition and will instead join the French club on a short-term deal.

O’Leary was in his second spell with his native province - he rejoined in 2015 and had played just two games off the bench this season - having spent three years at London Irish in between.

The Corkman, who won 24-caps for Ireland between 2007 and 2012, replaces Benoit Paillaugue in the Montpellier squad.
