Munster legend to retire after an incredible 14 seasons with Irish province

"I have always been determined to finish my career whilst still playing well and adding value to the jersey each time I get to put it on," he said.

"To be in a position to call time on such a fantastic experience, on my own terms, is one I am extremely grateful for.

"I believe the time is right for me, my family and for Munster Rugby to hang up my boots.

"I don’t want to reflect too much on the incredible journey just yet, as right now my focus is on performing to the best of my ability every time I’m handed that cherished red shirt.

"I am excited to help Munster continue to move forward and achieve our potential for the rest of the season."

Head Coach Johann van Graan added, "I only just said it recently, Billy will go down as a Munster legend in the history of the club, and rightly so.

"We all know the incredible character he is and how hard he works behind the scenes, always getting the job done.

"He has given his all to the jersey and all I can do is thank him for his service and commitment to Munster Rugby.

"We won’t dwell on it too much now, as ever the professional, Billy still has a job to do, helping to lead an ambitious group at this time."
