Munster have confirmed that they are releasing Duncan Williams, Mike Sherry, Dave O'Callaghan and James Hart at the end of the season.

O'Callaghan and Hart will play their rugby with French outfit Biarritz next season but Williams and Sherry are, for now, looking for new teams.

Scrum-half Williams comes to the end of an 11-year career with the province during which time he made 163 appearances in red and scored seven tries.

The 33-year-old played a lead role in Munster’s historic wins over Australia and the Maori All Blacks in Thomond Park, and enjoyed Magners League success in 2011.

Sherry, who is currently on loan at Gloucester, made his Munster debut in 2009 and scored 12 tries in 108 appearances for the province.

He was capped once for Ireland and battled back from injury to captain Munster when making his 100th Munster appearance against Ulster in April 2018.

A product of the Munster system, Dave O’Callaghan made his Munster debut as a 21-year-old against Ospreys in October 2011. The 29-year-old has gone on to score five tries in 85 appearances for the province.

Hart spent two seasons at Munster and scored two tries in 16 appearances. The 28-year-old scrum-half also made six appearances for Munster A in the British & Irish Cup and the Celtic Cup.

With Ronan O’Mahony retirement from professional rugby and Ian Keatley, Stephen Fitzgerald and Jaco Taute already confirmed for moves to respective PRO14 and Premiership clubs, it brings the total to eight players departing the province at the end of the season.
