Paul McMullan has made the move from Dundee United to Dundee immediately.
The winger agreed a pre-contract deal with United's neighbours earlier this month and found himself out of the first-team reckoning at Tannadice.
The 24-year-old former Celtic youth player has now completed a loan deal for the rest of the season to take him through to his summer transfer.
A statement from the Scottish Premiership club read: "We thank Paul for everything he has done for Dundee United and wish him all the very best in the future."
McMullan scored 19 goals in 122 appearances for United.
