Rising Offaly rugby star to join Pro16 team Birr rugby star moves closer to home Reporter: '); BIRR rugby star Jack Regan is to sign for Welsh club, Ospreys. It is a big career move for Regan who went to New Zealand after being let go by Ulster and has made a huge impression there. The lock initially joined Dunedin Sharks last March and showed his quality almost immediately. His performances here earned him selection on the Otago Mitre 10 Cup side and he played every game for them. It all represents a terrific comeback by Regan and he has answered his doubters quite spectacularly. He has really progressed in New Zealand. Dunedin Sharks are in the third tier of New Zealand club rugby but he hit the ground running here to earn selection on the regional side, Otago – they compete in the Mitre 10 Cup, a provincial competition in New Zealand.
