The Colours Match

There were also memorable encounters between UCD and TCD in the Leinster Senior Cup when the draw brought the sides together.

[citation needed] Following the Senior Cup win of UCD over DUFC in 1948 by a dropped goal to nil, the idea of a Colours match was discussed between Harry Thrift of Trinity and Sarsfield Hogan of UCD, who had served together on the International Rugby Board, on which basis each University club would award Colours for the season.

[1][2] Lengthy negotiations ensued and with the cooperation of the IRFU committee and of the Lansdowne and Wanderers RFCs a scheme for an annual Colours match was finally agreed.

Each University would act as the host in turn and be responsible for the management of the match and for the entertainment.

Colours Matches are also played between Trinity and UCD in women's rugby union and other sports, such as association football, Gaelic football, hurling, swimming, boxing, water polo, field hockey, golf, sailing, tennis, and fencing.
