The 30-year-old is a fans’ favourite at Leeds United and manager Simon Grayson is delighted to resolve the defender’s future.
“We’re delighted to get things finalised with Paddy,” Grayson told the club’s official website.
“He’s had a tough time, but we know what he is all about and what he brings to the team. He is a very important member of our squad.
“The deal shows the commitment of both the club and Paddy and it’s great to have him back with everyone after being out for so long.”
