League Two Team of the Week in March 2005 but later that month picked up a cartilage injury. He featured in one more match in
2004–05, which he finished with 10 appearances and two goals for Darlington. He was loaned out to York for a second time on 2 August 2005 on a six-month deal, so his progress could be monitored and could play regular first-team football. Darlington manager Hodgson said McGurk could have been brought back to the club when his loan at York ended, which he did having made 24 appearances and scored one goal for York. Following this "hugely successful" loan spell he made his last appearance of the season with Darlington after starting in a 1–1 home draw with
Wrexham on 6 May 2006 to cover for the suspended
Matthew Clarke.

substitute in a 0–0 away draw with
Ebbsfleet United on 8 March 2009. During the period of his injury, York signed defender
Shaun Pejic, whose form alongside
Daniel Parslow in central defence resulted in McGurk being unable to reaffirm his place in the team. He started in the
2009 FA Trophy Final at
Wembley Stadium on 9 May 2009, which York lost 2–0 to
Stevenage Borough. He finished the season with 45 appearances. although Parslow would wear the armband throughout the season. He picked up a hamstring injury during a 2–1 away win over

Gary Mills and McGurk explained he wanted to join Luton as he believed they offered him a better opportunity of achieving his ambition of returning to
the Football League. Luton manager
Richard Money eventually gave up on signing McGurk due to York demanding what he called a "ridiculous fee" for the player. However, another Luton bid was rejected after the transfer window opened in January 2011.

Southport on 29 January 2011. McGurk signed a new contract with York in March 2011, which contracted him to the club until the summer of 2013. An ankle ligament injury suffered in a 2–1 home victory over
