Cardiff City have signed midfielder Stuart O'Keefe from Crystal Palace.
The 23-year-old has joined for an undisclosed fee until 2017 and becomes Bluebirds boss Russell Slade's fourth signing of the transfer window.
O'Keefe has played three times for the Eagles this season and four for Blackpool while on loan.
He started Alan Pardew's first match in charge of Palace, in the FA Cup third-round win at non-league Dover.
Former Southend trainee O'Keefe is expected to make his debut for the visit of Derby County on Saturday.
