Former Ireland underage international Jack Regan has left Super Rugby's Highlanders to join Ospreys on a three-year deal.

The 24-year-old, who captained Leinster U18s and was a member of Ireland U20s Six Nations and Junior World Cup squad in 2017, moved to New Zealand after being released by Ulster and has caught the eye with a number of impressive performances.

After joining amateur side Dunedin Sharks, the Offaly native earned a place with Otago in the semi-pro Mitre 10 before being called up to play for the Highlanders in Super Rugby.

The lock made the Super Rugby Aotearoa team of the week in February on the same weekend as making his debut in the competition.

Regan said the chance to move to the Welsh club was a "great opportunity" and will compete with the likes Alun Wyn Jones, Adam Beard and Bradley Davies for a starting spot.

"There was interest from other clubs, but the squad there is building impressive performances and wins, and you just feel is heading for success," he said.

"I just want to be a part of that and play my role and add some value to the squad. I cannot wait to get to Swansea and to get going.

"This is just a great opportunity for me to develop as a player after my experiences with Ulster and the Highlanders."

Ospreys head coach Toby Booth said Regan’s journey to the top level was a testament to his character and a major reason for their interest in bringing him to the Liberty Stadium.

"One of the great things about Jack is his back story, he has battled through adversity to get to this stage in his career. His determination and resilience are massive attributes for us to utilise going forward."
