Ulster have been boosted by the news that Lewis Stevenson, Neil McComb and Sean Doyle have signed contract extensions.
Second-row, Stevenson, will stay at Ulster until at least the summer of 2016. His fellow lock, Neil McComb will remain until June 2015, while back-row forward, Sean Doyle, will represent the club until the end of the 2013/2014 season.
Lewis Stevenson, who is 28, has played 39 times for Ulster. His excellent form for the Province this season saw him included in the extended Ireland training squad for this year's Six Nations.
29 year-old, Neil McComb, has represented Ulster on 29 occasions. He signed his first senior contract for the 2010/2011 season and made his first Heineken Cup start for the Province in the away win over Castres last month.
Sean Doyle, who is 23, arrived at Ulster at the start of this season. He made a promising start to his career at Ravenhill, but a broken leg, sustained in a club game, has meant that it has been a frustrating six months for the Australian born open-side.
"I am delighted that these three players have committed to Ulster in the long-term," said Ulster director of rugby David Humphreys.
"Lewis and Neil have been important to us all season, while Sean showed in his first few games what an exciting prospect he is. I have no doubt that they will only get better as players and that is good for Ulster."
