Tyler Bleyendaal has agreed a new contract that will keep him with Munster until 2021 while Alby Mathewson has also penned a fresh deal that sees him remain at Thomond Park for the rest of the season.
New Zealander Bleyendaal has made 47 appearances in red since making his debut back in 2015, captaining the side on 11 occasions.
Munster’s Player of the Year in 2017, the playmaker will remain with the province for at least two more years.
Former All Black Mathewson has also signed a further extension - his current deal expired at the end of March - while tighthead prop Ciaran Parker, 23, will move from a development contract to a senior contract next season.
Academy pair Sean O’Connor and Keynan Knox have put pen to paper, the former advancing to the senior squad next season on a one-year development contract after completing his three years in the Academy.
In 2016 he featured for the Ireland Under-20s side that secured their best-ever finish as runners-up at the World Rugby Championship in England.
Knox has signed a three-year deal with the province that sees him continue with the Academy for a further year before advancing to the senior ranks.
