Ulster have strengthened their back row by signing Sean Reidy and Charlie Butterworth.
Butterworth has agreed a one-year contract, while Reid has signed a short-term deal with the Irish side after impressing with Counties Manukau Steelers in New Zealand.
"I can't wait to get started, it will be brilliant to be involved," Butterworth told the club's official site. "Ulster are one of the best teams in Europe, if not the world, at the moment and it was a no-brainer once David Humphreys offered me the contract.
"When I got the chance to go up and have a look at the facilities I was just really blown away. It's a top-class stadium; everything is state-of-the-art and I can't wait to start training."
The Ulstermen, who currently have three back-row players on tour with Ireland in Argentina, have also brought in South African duo Louis Ludik and Wiehahn Herbst.
