Roger Wilson has signed a new two-year contract with Ulster that will see him remain at Kingspan Stadium until the summer of 2017.
The 33 year-old, who can play anywhere in the back row, has represented Ulster 165 times.
In 2008 he moved to the English Premiership where he made 117 appearances for Northampton Saints, winning the European Challenge Cup and LV=Cup.
He won his only Ireland cap in 2005 against Japan and has represented Ireland A on 11 occasions.
“Ulster Rugby is a great place to be right now so I am pleased to have signed a new two year contract with the province,” said Wilson.
“Physically, I feel that I am as fit and well as I have ever been and I am looking forward to making a big contribution over the next two years.”
“Roger is one of the most consistent and hard-working members of our squad,” added team manager Bryn Cunningham.
“The fact that he has made 165 appearances for Ulster as well as having played more than 100 times for Northampton Saints illustrates his value to the teams he has represented and his considerable durability.”
“His experience of the game is invaluable, especially as we seek to bring through the next generation of players in Ulster and I am delighted that he has committed to the province for a further two seasons.”
