[6] McQuillan was in charge during the game that produced the infamous "spitgate" incident in the 2013 National Football League - when Donegal's reigning national footballer of the year Karl Lacey, who was injured that day, was hit by some spit from the mouth of a Tyrone fan.
[7] McQuillan later refereed the highly anticipated opening Ulster Championship clash between All-Ireland holders Donegal and Tyrone, winners in 2003, 2005 and 2008.
