Club Durcan originally played his club football for
Four Masters, sometimes playing outfield for the club. It was McDaid who put Durcan in touch with the Firhouse Road club. Durcan later explained: "I decided to play with Ballyboden to cut a bit of time coming and going from Donegal. I was up there all weekend for club and county but when I switched clubs I had more time around the weekends. I had been living on the northside but I had the connection with Ballyboden through Robbie. Then (manager)
Andy McEntee rang me himself. Robbie, I suppose, may have said something to him. I met Andy, I got on well with him and he brought me around the club." Durcan dislodged fellow goalkeepers Darragh Gogan and Conor Dooley to win Dublin and Leinster titles in 2015 and an All-Ireland Club Championship in 2016. He joined
Drumcliffe–Rosses Point and made his championship debut against
Tubbercurry at
Connolly Park in
Collooney on 1 August 2020, playing in the club's first
Sligo Senior Football Championship final the following month (lost to
Tourlestrane).
College Durcan notably saved two penalties for
Sligo IT during the 2005
Sigerson Cup, the first in the semi-final and the second in the final. Durcan played against
Armagh in the 2004 Ulster final at
Croke Park. He played in the 2006 Ulster final against the same opponents at the same venue. He was part of the Donegal team that won the
2007 National Football League.
Michael Boyle would later rival Durcan, occasionally taking his place on the first team. Boyle retained his starting place for the games against
Galway at
Markievicz Park and
Cork at
Croke Park. He played more league and championship matches under
Jim McGuinness's management than any other player. On 30 June 2012, in the Ulster semi-final against
Tyrone, Durcan received much credit after putting Donegal into the final with his outstretched foot. Donegal were three points ahead and it was practically the last action of the game. Durcan went low to his left and deflected
Martin Penrose's shot out off the post for a 45'. Tyrone manager
Mickey Harte said Durcan's last-gasp goal-saving intervention had denied Tyrone a replay. Durcan would later describe it as the most important save of his career. In 2013, Durcan made his 100th appearance for Donegal in the county's third
2013 National Football League game against Tyrone at
Healy Park. In the following game he contributed to Donegal's defeat of the mighty
Kerry by saving a penalty. In the Championship he helped his team to a third consecutive Ulster final. 2014 brought a third Ulster senior title and another extended run of games in the Championship. Somewhat unusually, he scored an
own goal in the 2014 All-Ireland quarter-final defeat of
Armagh at
Croke Park. He was involved in a
traffic collision during the
2015 National Football League campaign, though his injuries were not severe. After his team exited the 2015 championship, Durcan announced he would be moving to
Qatar. In 2019, Durcan returned home from Qatar sporting a long grey beard and rejoined the Donegal panel to contest for a place against
Shaun Patton and
Michael Lynch. He was reported to be living in Sligo since returning from Qatar. ==Training regime==
