Ulster have confirmed that Gareth Milasinovich will join the province in the summer from Worcester Warriors, where has made 19 appearances to date this season.
The 26-year-old prop was born in Johannesburg, South Africa, but qualifies for Ireland through his grandfather Norman McFarland, a former Ulster player.
Boss Dan McFarland was pleased to bolster his pack with the signing of Milasinovich.
He said: "Gareth is a big strong man who will provide us with another good option and enhance competition for places in the front row.
"We have been aware of his development since his move to Worcester and we’re looking forward to seeing him contribute to Ulster from next season."
Ulster have also announced that Alan O’Connor, Ross Kane, Dave Shanahan and Rob Lyttle have signed contract extensions.
All four are products of the Ulster academy.
