Ulster Rugby has been boosted by the news that forwards Lewis Stevenson, Neil McComb and Sean Doyle have signed contract extensions with the club.
Second-row Stevenson will stay at Ulster until at least the summer of 2016, fellow lock McComb will remain until June 2015 and back row Doyle until the end of the 2013-14 campaign.
"I'm delighted with this news," said Director of Rugby David Humphreys.
"I have no doubt they will only get better as players," he added.
Stevenson, 28, has played 39 times for Ulster and his excellent form for the province this season saw him included in the extended Ireland training squad for this year's Six Nations.
McComb, 29, has represented Ulster on 29 occasions, having signed his first senior contract for the 2010-11 season.
He made his first start for the Irish province in the away win over Castres last month.
Doyle, who is 23, arrived at Ulster at the start of this season and made a promising start to his career at Ravenhill.
A broken leg, sustained in a club game, has meant that it has been a frustrating six months for the Australian born open-side flanker.
