Marty Moore has signed a two-year contract extension with Ulster which will keep the prop at the province until the summer of 2022.
Former Leinster prop Moore has made 22 appearances for Ulster since joining from Wasps in the summer of 2018.
He had his first season at Ulster ended prematurely by an ankle ligament injury suffered in April.
The 28-year old feels at home in Belfast, "I’ve settled in really well at Ulster and have thoroughly enjoyed my time at the club, so I’m delighted to be able to get a deal sorted for another two years.
"Working with the coaches and wider support staff, I feel like I still have a lot of potential to improve, and I’m enjoying that process.
"We’re a club with big ambitions and I’m looking forward to playing my part in helping to achieve those.".
Head coach Dan McFarland is pleased to secure a player with such experience, "Marty has been a great addition to the squad. His ability and experience at set piece time has been demonstrated time and again, and has helped all our props make significant progress.
"His performances over the last two games have been excellent and he is keen to keep developing as part of our squad going forward."
Moore was named at tighthead for Friday evening's Heineken Champions Cup visit of Clermont-Auvergne to Kingspan Stadium.
