Connacht have completed the signings Ulster duo Niall O’Connor and Mark McCrea along with the re-signing of former favourite George Naoupu from Japan.

Out-half O’Connor, who played over 50 times for Ulster, and McCrea, who plays on the wing and played 25 times for the northern province will both join on a two-year contract at the end of the season.

And Naoupu will return to the Sportsground for the 2011/2012 season.

The 6’5, 115kg 27-year-old backrow joined Connacht in 2009 before moving to the Kobe Steelers in Japan last season.

He appeared 14 times in his six-month spell at Connacht, including scoring a try in the famous victory over Bourgoin in the Amlin Challenge Cup quarter-final last season.

Naoupu, who has represented New Zealand Schools, U19, Colts and 7’s, will rejoin Connacht on a two-year contract.
