Pompey complete deal for O'Brien
O'Brien's career statistics
Portsmouth have signed defender Andy O'Brien from Newcastle United for an undisclosed fee.
The 25-year-old Republic of Ireland international had spent four years on Tyneside after joining from Bradford City for £1m in 2001.
O'Brien made 172 appearances for Newcastle, 11 as a substitute.
He appeared to be staying at St James' Park when he signed a year's contract extension in January, but boss Graeme Souness has now allowed him to leave.
