Ireland internationals Jordi Murphy and Will Addison have signed two-year contract extensions with Ulster, who today confirmed their squad for the 2020/21 season.
The duo were due to be out of contract this summer but have both committed their future to the province.
Murphy has been at Ulster since joining them from Leinster in 2018, while former Sale Sharks star Addison also moved to Ravenhill in that season.
Ulster have moved to strengthen their squad with the signing on Ireland fly-half, Ian Madigan, who joins following a three-year stint with Bristol Bears whilst former All Blacks scrum-half, Alby Mathewson, returns to Irish shores following a successful spell with Munster.
Elsewhere, Jacob Stockdale, Sean Reidy and Matty Rea have all agreed deal to remain with the province.
Stewart Moore has committing to a new three-year deal which will see him graduate from the academy to spend one year as a development player, before being upgraded to a senior professional contract for the following two seasons.
Moore is one of two development players in a squad of 41 fully contracted players, 39 of which are Irish-qualified.
Head coach Dan McFarland believes he has the right blend and youth and experience in his squad.
He said: "Our desire to build on the successes of this season to-date is evidenced in our strong investment in talent from the current squad.
"Although it's an uncertain time for rugby, and all sport, I am confident our selection will stand us in good stead for when we are able to safely start the new season.
"Once again, the chosen line-up of players shines a light on the indigenous talent nurtured through the Academy by Kieran Campbell and his staff – and the role which it, along with the province's clubs and schools, continues to play in securing the future of Ulster Rugby.
"I would also like to take this opportunity to thank the players who are moving on from the squad.
"This includes Clive Ross, who earned 73 caps since joining the province on a development contract in 2014, along with 21-capped Angus Kernohan, and Zack McCall.
"Looking to the future, we look forward to welcoming the new additions to the squad, who are set to bring their own unique skills and talent, as we move towards a time when the 2020/21 season can kick-off."
