Munster have announced that Tommy O'Donnell has signed a two-year deal extension with the team and the IRFU that comes into effect from July 2014.
The 26-year-old, who made his debut for the province at 20, has two Ireland caps and was named Munster's Player of the Year in 2012/13.
"This is where I want to be and I enjoy playing my rugby here," O'Donnell told the Munster website.
"I know it hasn't been the best of starts to the season for me with injury, but like last year I just want to come back fighting and push on to the next level again."
Head Coach Rob Penney added: "Tommy is a great dynamic player and a huge asset to any side so we are particularly pleased that he has committed to Munster for another two years."
