The Northern Ireland international spent much of the first half of the Championship campaign on loan at Elland Road, but returned to the North East this month. Ben Parker has been filling in at left-back of late for the Whites, however, Leeds have brokered a deal that sees McCartney back in West Yorkshire until the summer. The 29-year-old defender made 17 appearances for Simon Grayson's side this season and played a key role in their lengthy unbeaten run which ended recently against Cardiff. "I'm delighted we've been able to bring George back until the end of the season. He did well over the course of his last loan spell and I know what he can bring to the table," Grayson told the club's official website. United chairman Ken Bates added: "The additional revenue earned from the Arsenal game has helped make this loan possible as we continue to invest both on and off the field."
