Alan O’Connor and Andy Warwick are among eight players who will leave Ulster Rugby at the end of the 2024-25 season.
The pair are two of 11 players who have represented the province more than 200 times.
Dublin native O’Connor, who has regularly captained the side, joined Ulster in 2012 after representing the Ireland Under-20s and was named the side’s player of the year in the 2020-21 season.
Warwick, who came through the club’s academy, made his senior debut in February 2014.
“Al [O’Connor] and Waz [Warwick] have been superb role models in the way they go about their work with a no-nonsense attitude and total commitment to the jersey over the years,” said Ulster’s general manager Bryn Cunningham.
“Both players hit the milestone of reaching over 200 caps for Ulster Rugby earlier this season, becoming members of that special club.”
As well as previously confirmed exits for John Cooney, Kieran Treadwell and Reuben Crothers, prop Corrie Barrett, scrum-half Michael McDonald and flanker Matty Rea will also be departing Kingspan Stadium at the end of the season.
