He played for Scotland in the third of the
unofficial matches prior to the first official international match, a 1–1 draw on 25 February 1871 playing under the pseudonym "F. Maclean". He won his solitary England cap playing on the left of midfield in
England's first ever international match against
Scotland on 30 November 1872. The University reached the
1874 FA Cup Final and (with Maddison now on the right) this time they were successful, defeating the
Royal Engineers by two goals to nil. Maddison was involved in the move which resulted in the second goal, when he, together with
Cuthbert Ottaway and
Robert Vidal, "dribbled their way to the Engineers' goal, where
Frederick Patton was waiting to slide the ball between the posts." Maddison also played for amateur club
Crystal Palace (not the later professional club) and the
Civil Service, and in representative matches for
London and The South versus The North. ==Life outside football==
