He had also started Mickey Moran's first game in charge of Donegal, a league win at home to Offaly in October 2000.[5]
Sweeney made his championship debut against Antrim in 1998. He missed Donegal's National Football League in 2007 after leaving the squad at the end of the previous season due to a disagreement with the then manager Brian McIver. He also never won the Ulster Senior Football Championship during his career. However, he did win the 2009 Dr McKenna Cup with Donegal and the 2004 Railway Cup with Ulster. Sweeney retired from playing for Donegal in 2010 after more than a decade and 96 games.[6]
His brother Adrian also played for An Clochán Liath and Donegal.[7]

In the semi-final, 14-man Donegal, who had Raymond Sweeney harshly sent off for a second booking three minutes into the second half, led reigning champions Armagh until the dying embers, before losing 2–10 to 1–9. Oisin McConville's last minute penalty eventually buried brave Donegal.

Our Vocational School team won the All-Ireland title against Leitrim in the curtain raiser [to the NFL final in 1995 which, in reference to the column title, was played one week before Donegal knocked out Down in the Ulster SFC preliminary round, 25 years before the column was written]. Brian McLaughlin, Eamon Reddin, Barry Monaghan and Ray Sweeney were all on that team and would go on to represent the county at senior level.
