West Ham defender Joey O'Brien has signed a new contract to keep him at the club until 2016.
O'Brien played under Sam Allardyce at Bolton and was brought to Upton Park by the Hammers boss in 2011.
The club announced on their official Twitter feed: “West Ham United are pleased to announce that Joey O'Brien has signed a new contract with the club until summer 2016.”
O'Brien, 26, has five caps for the Republic of Ireland and has played 16 times in the Premier League this season, scoring twice. He was also part of the side that helped clinch promotion from the Championship last term.
He made 70 appearances in all competitions over seven years at Bolton, including playing in the Europa League.
He also had two separate loan spells at Sheffield Wednesday and he was hampered by a serious knee injury in the seasons before his departure to the Hammers.
