Munster have confirmed that Billy Holland has penned a new two-year contract, while Ian Nagle has joined Premiership side Newcastle Falcons on a short-term loan.
Holland made his Munster debut in 2007 against Llanelli Scarlets, and the academy graduate made his Heineken Cup debut against Northampton Saints in April 2010.
Holland has won 83 caps for Munster, playing both second row and back row.
He featured in every single PRO12 game last season and has played ten games so far this season.
Nagle moves to the Falcons on a three-month loan basis.
